DAC7574IDGSG4 .

The DAC7574IDGSG4 is a 12-bit quad voltage output Digital-to-analogue Converter with I²C interface. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC7574 utilizes an I²C compatible two wire serial interface supporting high-speed interface mode with address support of up to four DACs for a total of 16 channels on the bus. The DAC uses VDD and GND to set the output range of the DAC. The DAC 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 DAC 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 3mW at VDD=5V reducing to 1µW in power-down mode.
