DAC8532

    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 V_DD= 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 inter face, that reduces the current consumption of the device to 200nA at 5V.

    The low-power consumption of DAC8532 in normal operation makes it ideally suited to portable battery-operated equipment and other low-power applications. The power consumption is 2.5mW at 5V, reducing to 1µW in power-down mode.
