DESCRIPTION
●The DAC8554 is a 16-bit, quad channel, voltage output, digital-to-analog converter (DAC), offering low-power operation and a flexible serial host interface. It offers monotonicity, good linearity, and exceptionally low glitch. Each on-chip precision output amplifier allows rail-to-rail output swing to be achieved over the supply range of 2.7 V to 5.5 V. The device supports a standard 3-wire serial interface capable of operating with input data clock frequencies up to 50 MHz for IOVDD = 5 V.
