Download the DAC1221 datasheet PDF.
This datasheet also covers the DAC1222 variant, as both devices belong to the same binary multiplying d/a converter family and are provided as variant models within a single manufacturer datasheet.
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 coef
