General Description

The MAX5510/MAX5511 are single, 8-bit, ultra-low-

power, voltage-output, digital-to-analog converters

(DACs) offering rail-to-rail buffered voltage outputs. The

DACs operate from a 1.8V to 5.5V supply and consume

less than 6µA, making them desirable for low-power

and low-voltage applications. A shutdown mode

reduces overall current, including the reference input

current, to just 0.18µA. The MAX5510/MAX5511 use a

3-wire serial interface that is compatible with SPI™,

QSPI™, and MICROWIRE™.

At power-up, the MAX5510/MAX5511 outputs are dri-

ven to zero scale, providing additional safety for appli-

cations that drive valves or for other transducers that

must be off during power-up. The zero-scale outputs

enable glitch-free power-up.

The MAX5510 accepts an external reference input. The

MAX5511 contains an internal reference and provides

an external reference output. Both devices have force-

sense-configured output buffers.

The MAX5510/MAX5511 are available in a 4mm x 4mm

x 0.8mm, 12-pin, thin QFN package and are guaranteed

over the extended -40°C to +85°C temperature range.

For 12-bit compatible devices, refer to the MAX5530/

MAX5531 data sheet. For 10-bit compatible devices,

refer to the MAX5520/MAX5521 data sheet.

MAX5510/MAX5511 +1.8V to +5.5V, Ultra-Low-Power, 8-Bit, Voltage-Output DACs Power Modes The MAX5510/MAX5511 feature two power modes to conserve power during idle periods. In normal operation, the device is fully operational. In shutdown mode, the device is completely powered down, including the internal voltage reference in the MAX5511. The MAX5511 also offers a standby mode where all circuitry is powered down except the internal voltage reference.

The low current consumption of the devices makes the MAX5510/MAX5511 ideal for battery-powered applications. See the circuit in Figure 5 for an illustration of how to configure the MAX5510 to bias a current-output transducer.

+1.8V to +5.5V, Ultra-Low-Power, 8-Bit, Voltage-Output DACs MAX5510/MAX5511 Unipolar Output Figure 7 shows the MAX5510 in a unipolar output configuration with unity gain. Table 4 lists the unipolar output codes. REF OUT DAC TO ADC IF Bipolar Output The MAX5510 output can be configured for bipolar operation, as shown in Figure 8. The output voltage is given by the following equation: VOUT = VREF x [(NA - 128) / 128] where NA represents the numeric value of the DAC’s binary input code.

+1.8V to +5.5V, Ultra-Low-Power, 8-Bit, Voltage-Output DACs Bypass the power supply with a 0.1µF capacitor to GND. Minimize lengths to reduce lead inductance. If noise becomes an issue, use shielding and/or ferrite beads to increase isolation. For the thin QFN package, connect the exposed paddle to ground. Layout Considerations Digital and AC transient signals coupling to GND can create noise at the output. Use proper grounding techniques, such as a multilayer board with a low-inductance ground plane.
