16-Bit, Dual Channel, Low Power D-to-A Converter W/ Serial I/F And Rail-to-Rail Voltage Output

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.
The low-power consumption of this device 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 1W in power-down mode.
The DAC8532 is available in a MSOP-8 package with a specified operating temperature range of ?40C to +105C.
