The DAC6571 is a low-power, single-channel, 10-bit buffered voltage output digital-to-analog converter (DAC). Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC6571 utilizes an I2C-compatible, two-wire serial interface that operates at clock rates up to 3.4 MBPS with address support of up to two DAC6571s on the same data bus.

The output voltage range of the DAC is 0 V to VDD. The DAC6571 incorporates a power-on-reset circuit that ensures that the DAC output powers up at zero volts and remains there until a valid write to the device takes place. The DAC6571 contains a power-down feature, accessed via the internal control register, that reduces the current consumption of the device to 50 nA at 5 V.

The low power consumption of this part in normal operation makes it ideally suited for portable battery operated equipment. The power consumption is less than 0.7 mW at VDD = 5 V reducing to 1 µW in power-down mode.

The DAC7571/6571/5571 are 12/10/8-bit, single-channel I2C DACs from the same family. The DAC7574/6574/5574 and DAC7573/6573/5573 are 12/10/8-bit, quad-channel I2C DACs. Also see the DAC8571/8574 for single/quad-channel, 16-bit I2C DACs.
