MCP4011/2/3/4 3.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 3-1.
MCP4011/2/3/4 3.6 Chip Select (CS) The CS pin is the chip select input. Forcing the CS pin to VIL enables the serial commands. These commands can increment and decrement the wiper. Forcing the CS pin to VIHH enables the high-voltage serial commands. These commands can increment and decrement the wiper and are compatibe with the MCP402X devices. The wiper is saved to volatile memory (RAM). 3.
MCP4011/2/3/4 4.0 GENERAL OVERVIEW EQUATION 4-1: The MCP4011/2/3/4 devices are general purpose digital potentiometers intended to be used in applications where a programmable resistance with moderate bandwidth is desired.
MCP4011/2/3/4 4.2 Power-up 4.3 When the device powers up (rising VDD crosses the Trip Point Voltage (VTP)), the “default” wiper setting is restored. Table 4-1 shows the default value loaded into the wiper on POR/BOR. TABLE 4-1: DEFAULT POR WIPER SETTING SELECTION Default POR Wiper Setting Wiper Code Typical RAB Value -202 Mid-scale 1Fh 2.1 kΩ -502 Mid-scale 1Fh 5.0 kΩ -103 Mid-scale 1Fh 10.0 kΩ -503 Mid-scale 1Fh 50.
MCP4011/2/3/4 5.0 SERIAL INTERFACE 5.1 Overview 5.2 The MCP4011/2/3/4 utilizes a simple 2-wire interface to increment or decrement the digital potentiometer’s wiper terminal (W). This interface uses the CS and U/D pins. The CS pin is the Chip Select input, while the U/D pin is the Up/Down input. The Increment/Decrement protocol enables the device to move one step at a time through the range of possible resistance values. The wiper value is initialized with the “default” value upon power-up.
MCP4011/2/3/4 5.2.1 INCREMENT When the device voltage falls below the RAM retention voltage of the device, the wiper state may be corrupted. When the device returns to the operating range, the wiper will be loaded with the default POR wiper setting. This mode is achieved by initializing the U/D pin to a high state (VIH) prior to achieving a low state (VIL) on the CS pin. Subsequent rising edges of the U/D pin increment the wiper setting toward terminal A. This is shown in Figure 5-1.
MCP4011/2/3/4 5.2.2 Note: INCREMENT (FOR MCP402X COMPATIBILITY) When the device voltage falls below the RAM retention voltage of the device, the wiper state may be corrupted. When the device returns to the operating range, the wiper will be loaded with the Default POR wiper setting. This command allows compatibility with the MCP402X family, which supports updating of the non-volatile wiper setting. After the CS pin is driven to VIH (from VIL), any other serial command may immediately be entered.
MCP4011/2/3/4 5.2.3 DECREMENT When the device voltage falls below the RAM retention voltage of the device, the wiper state may be corrupted. When the device returns to the operating range, the wiper will be loaded with the default POR wiper setting. This mode is achieved by initializing the U/D pin to a low state (VIL) prior to achieving a low state (VIL) on the CS pin. Subsequent rising edges of the U/D pin will decrement the wiper setting toward terminal B. This is shown in Figure 5-3.
MCP4011/2/3/4 5.2.4 Note: DECREMENT (FOR MCP402X COMPATIBILITY) When the device voltage falls below the RAM retention voltage of the device, the wiper state may be corrupted. When the device returns to the operating range, the wiper will be loaded with the default POR wiper setting. This command allows compatibility with the MCP402X family, which supports updating of the non-volatile wiper setting. After the CS pin is driven to VIH (from VIL), any other serial command may immediately be entered.
MCP4011/2/3/4 5.2.5 Note: HIGH-VOLTAGE INCREMENT 1 (FOR MCP402X COMPATIBILITY) After the CS pin is driven to VIH (from VIL), any other serial command may immediately be entered. Note: This command allows compatibility with the MCP402X family, which supports updating of the non-volatile wiper setting with the WiperLock Technology feature. The wiper value will not overflow. That is, once the wiper value equals 0x3F, subsequent increment commands are ignored.
MCP4011/2/3/4 5.2.6 Note: HIGH-VOLTAGE INCREMENT 2 (FOR MCP402X COMPATIBILITY) After the CS pin is driven to VIH (from VIL), any other serial command may immediately be entered. Note: This command allows compatibility with the MCP402X family, which supports updating of the non-volatile wiper setting with the WiperLock Technology feature. The wiper value will not overflow. That is, once the wiper value equals 0x3F, subsequent increment commands are ignored.
MCP4011/2/3/4 5.2.7 Note: HIGH-VOLTAGE DECREMENT 1 (FOR MCP402X COMPATIBILITY) After the CS pin is driven to VIH (from VIL), any other serial command may immediately be entered. Note: This command allows compatibility with the MCP402X family, which supports updating of the non-volatile wiper setting with the WiperLock Technology feature. The wiper value will not underflow. That is, once the wiper value equals 0x00, subsequent decrement commands are ignored.
MCP4011/2/3/4 5.2.8 Note: HIGH-VOLTAGE DECREMENT 2 (FOR MCP402X COMPATIBILITY) After the CS pin is driven to VIH (from VIL), any other serial command may immediately be entered. Note: This command allows compatibility with the MCP402X family, which supports updating of the non-volatile wiper setting with the WiperLock Technology feature. The wiper value will not underflow. That is, once the wiper value equals 0x00, subsequent decrement commands are ignored.
MCP4011/2/3/4 5.3 CS High Voltage The CS pin is High-Voltage (VIHH) tolerant, like the MCP402X. This allows the MCP401X to be used in MCP402X applications without needing to change other portions of the application circuit. 6.0 RESISTOR Digital potentiometer applications can be divided into two categories: Figure 6-1 shows a block diagram for the MCP401X resistors. A RW (1) RW (1) RW (1) N = 62 Typical Resistance (Ω) Total (RAB) Step (RS) MCP401X-203E 2100 33.33 MCP401X-503E 5000 79.
MCP4011/2/3/4 6.1 Resistor Configurations 6.1.1 6.1.2 RHEOSTAT CONFIGURATION When used as a rheostat, two of the three digital potentiometer’s terminals are used as a resistive element in the circuit. With terminal W (wiper) and either terminal A or terminal B, a variable resistor is created. The resistance will depend on the tap setting of the wiper and the wiper’s resistance. The resistance is controlled by changing the wiper setting. The unused terminal (B or A) should be left floating.
MCP4011/2/3/4 6.2 Wiper Resistance The slope of the resistance has a linear area (at the higher voltages) and a non-linear area (at the lower voltages), where resistance increases faster than the voltage drop (at low voltages). Wiper resistance is the series resistance of the wiper. This resistance is typically measured when the wiper is positioned at either zero-scale (00h) or full-scale (3Fh).
MCP4011/2/3/4 6.3 Operational Characteristics Understanding the operational characteristics of the device’s resistor components is important to the system design. 6.3.1 6.3.1.1 6.3.1.2 Differential Non-Linearity (DNL) DNL error is the measure of variations in code widths from the ideal code width. A DNL error of zero would imply that every code is exactly 1 LSb wide.
MCP4011/2/3/4 6.3.2 MONOTONIC OPERATION Monotonic operation means that the device’s resistance increases with every step change (from terminal A to terminal B or terminal B to terminal A). The wiper resistance is different at each tap location. When changing from one tap position to the next (either increasing or decreasing), the ΔRW is less than the ΔRS. When this change occurs, the device voltage and temperature are “the same” for the two tap positions.
MCP4011/2/3/4 7.0 DESIGN CONSIDERATIONS In the design of a system with the MCP401X devices, the following considerations should be taken into account: • The Power Supply • The Layout 7.1 Power Supply Considerations The typical application will require a bypass capacitor in order to filter high-frequency noise, which can be induced onto the power supply's traces. The bypass capacitor helps to minimize the effect of these noise sources on signal integrity.
MCP4011/2/3/4 8.0 APPLICATIONS EXAMPLES VDD Non-volatile digital potentiometers have a multitude of practical uses in modern electronic circuits. The most popular uses include precision calibration of set point thresholds, sensor trimming, LCD bias trimming, audio attenuation, adjustable power supplies, motor control overcurrent trip setting, adjustable gain amplifiers and offset trimming.
MCP4011/2/3/4 8.2 Operational Amplifier Applications VDD VIN Figure 8-3, Figure 8-4 and Figure 8-5 illustrate typical amplifier circuits that could replace fixed resistors with the MCP4011/2/3/4 to achieve digitally-adjustable analog solutions. R3 A VIN MCP4011 A R3 MCP4012 FIGURE 8-4: Trimming Offset and Gain in a Non-Inverting Amplifier.
MCP4011/2/3/4 8.3 Temperature Sensor Applications VDD Thermistors are resistors with very predictable variation with temperature. Thermistors are a popular sensor choice when a low-cost, temperature-sensing solution is desired. Unfortunately, thermistors have non-linear characteristics that are undesirable, typically requiring trimming in an application to achieve greater accuracy. There are several common solutions to trim and linearize thermistors.
MCP4011/2/3/4 9.0 DEVELOPMENT SUPPORT 9.1 Evaluation/Demonstration Boards Currently there are three boards that are available that can be used to evaluate the MCP401X family of devices. 1. The MCP402X Digital Potentiometer Evaluation Board kit (MCP402XEV) contains a simple demonstration board utilizing a PIC10F206, the MCP401X and a blank PCB, which can be populated with any desired MCP4011/2/3/4 device in a SOT-23-5, SOT-23-6 or 150 mil SOIC 8-pin package.
