DAC9881 - Texas Instruments

DAC9881 Digital-to-Analog Converter

The DAC9881 is an 18-bit, single-channel, voltageoutput digital-to-analog converter (DAC). The device features 18-bit monotonicity, excellent linearity, very low-noise, and fast settling time. The on-chip precision output amplifier allows for a rail-to-rail output swing to be achieved over the full supply range of 2.7 V to 5.5 V. The device supports a standa.
