DESCRIPTION
The DAC7571 is a low-power, single channel, 12-bit
buffered voltage output DAC. Its on-chip precision
output amplifier allows rail-to-rail output swing to be
achieved. The DAC7571 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
DAC7571s on the same data bus.
The output voltage range of the DAC is set to VDD.
The DAC7571 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 DAC7571 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 is available in a 6-lead SOT 23
package.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during
storage or handling to prevent electrostatic damage to the MOS gates.
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.
