DAC1220 Datasheet | National Semiconductor

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 m W max) and low output leakages (200 n A max) The digital inputs are patible with DTL TTL logic levels as well as full CMOS logic level swings This part bined with an external amplifier and voltage reference can be used as a standard D A converter however it is also very attractive for multiplying...
