DAC121C085 12-Bit Micro Power Digital-to-Analog Converter

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 op.
