DAC8311 DAC8411 www.ti.com SBAS439B – AUGUST 2008 – REVISED MAY 2013 THEORY OF OPERATION DAC SECTION VREF The DAC8311 and DAC8411 are fabricated using TI's proprietary HPA07 process technology. The architecture consists of a string DAC followed by an output buffer amplifier. Because there is no reference input pin, the power supply (AVDD) acts as the reference. Figure 72 shows a block diagram of the DAC architecture.

DAC8311 DAC8411 SBAS439B – AUGUST 2008 – REVISED MAY 2013 www.ti.com SERIAL INTERFACE (for 14-Bit DAC8311) The DAC8311 has a 3-wire serial interface (SYNC, SCLK, and DIN) compatible with SPI, QSPI, and Microwire interface standards, as well as most DSPs. See the 14-bit Serial Write Operation timing diagram for an example of a typical write sequence. At this point, the SYNC line may be kept low or brought high.

DAC8311 DAC8411 www.ti.com SBAS439B – AUGUST 2008 – REVISED MAY 2013 SERIAL INTERFACE (for 16-Bit DAC8411) The DAC8411 has a 3-wire serial interface (SYNC, SCLK, and DIN) compatible with SPI, QSPI, and Microwire interface standards, as well as most DSPs. See the 16-bit Serial Write Operation timing diagram for an example of a typical write sequence. At this point, the SYNC line may be kept low or brought high.
PAGE 24
DAC8311 DAC8411 SBAS439B – AUGUST 2008 – REVISED MAY 2013 www.ti.com POWER-ON RESET TO ZERO-SCALE The DAC8x11 contains a power-on reset circuit that controls the output voltage during power-up. On power-up, the DAC register is filled with zeros and the output voltage is 0V. The DAC register remains that way until a valid write sequence is made to the DAC. This design is useful in applications where it is important to know the state of the output of the DAC while it is in the process of powering up.
PAGE 25
DAC8311 DAC8411 www.ti.com SBAS439B – AUGUST 2008 – REVISED MAY 2013 APPLICATION INFORMATION USING THE REF5050 AS A POWER SUPPLY FOR THE DAC8x11 As a result of the extremely low supply current required by the DAC8x11, an alternative option is to use a REF5050 +5V precision voltage reference to supply the required voltage to the part, as shown in Figure 77. This option is especially useful if the power supply is too noisy or if the system supply voltages are at some value other than 5V.

DAC8311 DAC8411 SBAS439B – AUGUST 2008 – REVISED MAY 2013 www.ti.com MICROPROCESSOR INTERFACING DAC8x11(1) Microwire DAC8x11 to 8051 Interface CS SYNC Figure 79 shows a serial interface between the DAC8x11 and a typical 8051-type microcontroller. The setup for the interface is as follows: TXD of the 8051 drives SCLK of the DAC8x11, while RXD drives the serial data line of the part. The SYNC signal is derived from a bit programmable pin on the port. In this case, port line P3.3 is used.

DAC8311 DAC8411 www.ti.com SBAS439B – AUGUST 2008 – REVISED MAY 2013 LAYOUT A precision analog component requires careful layout, adequate bypassing, and clean, well-regulated power supplies. The DAC8x11 offers single-supply operation; it will often be used in close proximity with digital logic, microcontrollers, microprocessors, and digital signal processors.

STATIC PERFORMANCE Static performance parameters are specifications such as differential nonlinearity (DNL) or integral nonlinearity (INL). These are dc specifications and provide information on the accuracy of the DAC.

DAC8311 DAC8411 www.ti.com SBAS439B – AUGUST 2008 – REVISED MAY 2013 Gain Temperature Coefficient Digital Feedthrough The gain temperature coefficient is defined as the change in gain error with changes in temperature. The gain temperature coefficient is expressed in ppm of FSR/°C. Digital feedthrough is defined as impulse seen at the output of the DAC from the digital inputs of the DAC. It is measured when the DAC output is not updated.

DAC8311 DAC8411 SBAS439B – AUGUST 2008 – REVISED MAY 2013 www.ti.com Signal-to-Noise plus Distortion (SINAD) DAC Output Noise SINAD includes all the harmonic and outstanding spurious components in the definition of output noise power in addition to quantizing any internal random noise power. SINAD is expressed in dB at a specified input frequency and sampling rate, fS. DAC output noise is defined as any voltage deviation of DAC output from the desired value (within a particular frequency band).
