The DAC8532 is a dual 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 2.7V 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 DAC8532 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 DAC8532 provides a flexible power-down feature, accessed over the serial interface, that reduces the current consumpTIon of the device to 200nA at 5V.
