DAC8534IPWG4

The DAC8534IPWG4 is a quad channel 16-bit Digital-to-analog Converter (DAC) offering 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 5VDD. The DAC8534 requires an external reference voltage to set the output range of 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 DAC8534 provides a per channel power-down feature, accessed over the serial interface, that reduces the current consumption to 200nA per channel at 5V. The low-power consumption of this device in normal operation makes it ideally suited to portable battery-operated equipment and other low-power applications.
