Texas Instruments DAC5571

the dac5571 is a low-power single-channel 8-bit buffered voltage output dac. its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. the dac5571 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 dac5571s on the same data bus. the output voltage range of the dac is 0 v to vdd. the dac5571 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 dac5571 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. view all in datasheet
