DESCRIPTION
The DAC7573 is a low-power, quad channel, 12-bit
buffered voltage output DAC. Its on-chip precision
output amplifier allows rail-to-rail output swing to be
achieved. The DAC7573 utilizes an I2C compatible
two wire serial interface supporting high-speed
interface mode with address support of up to sixteen
DAC7573s for a total of 64 channels on the bus.
The DAC7573 requires an external reference voltage
to set the output range of the DAC. The DAC7573
incorporates a power-on-reset circuit that ensures
that the DAC output powers up at zero volts and
remains there until a valid write takes place in the
device. The DAC7573 contains a power-down fea-
ture, accessed via the internal control register, that
reduces the current consumption of the device to 200
nA at 5 V.
The low power consumption of this part in normal
operation makes it ideally suited to portable battery
operated equipment. The power consumption is less
than 3 mW at VDD=5 V reducing to 1 µW in
power-down mode.
The DAC7573 is available in a 16-lead TSSOP
package.

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.
