DAC1220E

The DAC1220E is a 20-bit delta-sigma low power Digital-to-analogue Converter offers 20-bit monotonic performance over the specified temperature range. It utilizes delta-sigma technology to achieve inherently 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 maximum. 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 signal allows for selection of the appropriate D/A converter.
