Description

The DAC6571 is a low-power, single channel, 10-Bit buffered voltage output DAC. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC6571 utilizes an I ² C 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 V_DD .
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 V = 5 V_DD reducing to 1 W in power-down mode.
DAC7571/6571/5571 are 12/10/8 bit single channel I ²C DACs from the same family. DAC7574/6574/5574 and DAC7573/6573/5573 are 12/10/8 bit quad channel I ² C DACs. Also see DAC8571/8574 for single/quad channel 16-bit I ² C DACs.
