DAC5574IDGS

The DAC5574IDGS is a low-power quad channel 8-bit buffered voltage output Digital-to-analog Converter (DAC) with on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC5574 utilizes an I?C compatible two wire serial interface supporting high-speed interface mode with address support of up to four DAC5574 for a total of 16 channels on the bus. The DAC5574 uses VDD and GND to set the output range of the DAC. The DAC5574 incorporates a power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid write takes place to the device. The DAC5574 contains a per-channel power-down feature, accessed via the internal control register, reducing the current consumption of the device to 200nA at 5V. The low power consumption of this part in normal operation makes it ideally suited to portable battery operated equipment. The power consumption is less than 3mW at 5VDD reducing to 1µW in power-down mode.
