DESCRIPTION
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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.
