DAC101C085 Datasheet 12-bit Micro Power Digital-to-analog Converter

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: DAC121C081/ DAC121C085 12-Bit Micro Power Digital-to-Analog Converter with an I2C-Compatible Interface www.DataSheet4U.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The DAC121C081 is a 12-bit, single channel, voltage-output digital-to-analog converter (DAC) that operates from a +2.7V to 5.5V supply.

The output amplifier allows rail-to-rail output swing and has an 8.5usec settling time.

The DAC121C081 uses the supply voltage as the reference to provide the widest dynamic output range and typically consumes 132uA while operating at 5.0V.

Key Features
