The DAC8552IDGKTG4 is a 16-bit voltage output Digital-to-analogue Converter offers low power operation and a flexible serial host interface. Each on-chip precision output amplifier allows rail-to-rail output swing to be achieved over the supply range of 2.7 to 5.5V. The device supports a standard 3-wire serial interface capable of operating with input data clock frequencies up to 30MHz for VDD=5V. The DAC requires an external reference voltage to set the output range of each DAC channel. Also incorporated into the device is a power-on reset circuit which ensures that the DAC outputs power up at zero-scale and remain there until a valid write takes place. The DAC provides a flexible power-down feature, accessed over the serial interface that reduces the current consumption of the device to 700nA at 5V.
