The Texas Instruments DAC9881 Digital-to-Analog Converter (DAC) improves system performance and simplifies designs by providing the industry's highest accuracy and 18-bit monotonic performance. This TI device offers ±2 LSB integral nonlinearity and ±1 LSB differential nonlinearity along with low noise and fast settling time. The DAC9881 includes an on-chip precision output amplifier that allows rail-to-rail output swing to be achieved over the full supply range of 2.7V to 5.5V.
