DAC7573IPW

The DAC7573IPW is a low-power quad-channel 12-bit buffered voltage output Digital-to-Analog (DAC) with on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC7573 utilizes an I²C compatible two wire serial interface supporting high-speed interface mode with address support of up to sixteen DAC7573 for a total of 64-channel on the bus. The DAC7573 requires an external reference voltage to set the output range of the DAC. The DAC7573 incorporates a power-on-reset circuit that ensures that the DAC output powers up at 0V and remains there until a valid write takes place to the device. The DAC7573 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 5VDD reducing to 1µW in power-down mode.
