DAC1020 General Description

The DAC1020 and the DAC1220 are, respectively, 10 and 12-bit binary multiplying digital-to-analog converters. A deposited thin film R-2R resistor ladder divides the reference current and provides the circuit with excellent temperature tracking characteristics (0.0002%/§C linearity error temperature coefficient maximum). The circuit uses CMOS current switches and drive circuitry to achieve low power consumption (30 mW max) and low output leakages (200 nA max). The digital inputs are compatible with DTL/TTL logic levels as well as full CMOS logic level swings. This part, combined with an external amplifier and voltage reference, can be used as a standard D/A converter; however, it is also very attractive for multiplying applications (such as digitally controlled gain blocks) since its linearity error is essentially independent of the voltage reference. All inputs are protected from damage due to static discharge by diode clamps to Va and ground.

This part is available with 10-bit (0.05%), 9-bit (0.10%), and 8-bit (0.20%) non-linearity guaranteed over temperature (note 1 of electrical characteristics). The DAC1020, DAC1021 and DAC1022 are direct replacements for the 10- bit resolution AD7520 and AD7530 and equivalent to the AD7533 family. The DAC1220 and DAC1222 are direct re- placements for the 12-bit resolution AD7521 and AD7531 family.
