The DAC8574 is a low-power, quad channel, 16-bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC8574 utilizes an I²C compatible two wire serial interface supporting high-speed interface mode with address support of up to sixteen DAC8574’s for a total of 64 channels on the bus.

The DAC8574 requires an external reference voltage to set the output range of the DAC. The DAC8574 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 DAC8574 contains a power-down feature, accessed via the internal control register, that reduces 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 5mW at VDD = 5V reducing to 1µW in power-down mode.

The DAC8574 is available in an 16-lead TSSOP package.
