20-Bit Delta-Sigma Low Power Digital-To-Analog Converter

The DAC1220 is a 20-bit digital-to-analog (D/A) converter offering 20-bit monotonic performance over the specified temperature range. It utilizes delta-sigma technology to achieve inher 1396 ently linear performance in a small package at very low power. The resolution of the device CAN be programmed to 20 bits for Full-Scale, settling to 0.003% within 15ms typical, or 16 bits for Full-Scale, settling to 0.012% within 2ms max. The output range is two times the external reference voltage. On-chip calibration circuitry dramatically reduces low offset and gain errors.
The DAC1220 features a synchronous serial interface; in single-converter applications, the serial Interface CAN be accomplished with just two wires, allowing low-cost isolation. For multiple converters, a CS
