DAC1222 Datasheet

Features and benefits

Y Y Y Y Y Y Y Y Y Y Linearity specified with zero and full-scale adjust only Non-linearity guaranteed over temperature Integrated thin film on CMOS structure 10-bit or 1.

Application

(such as digitally controlled gain blocks) since its linearity error is essentially independent of the voltage reference.

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 character.
