NOTE: (1) Stresses above those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. Exposure to absolute maximum
conditions for extended periods may affect device reliability.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments 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.

DESCRIPTION
Analog output voltage from DAC. The output ampli-
fier has rail-to-rail operation.
Ground reference point for all circuitry on the part.
Power Supply Input, +2.7V to 5.5V.
Serial Data Input. Data is clocked into the 16-bit
input shift register on the falling edge of the serial
clock input.
Serial Clock Input. Data can be transferred at rates
up to 30MHz.
Level triggered control input (active LOW). This is
the frame sychronization signal for the input data.
When SYNC goes LOW, it enables the input shift
register and data is transferred in on the falling
edges of the following clocks. The DAC is updated
following the 16th clock cycle unless SYNC is taken
HIGH before this edge, in which case the rising
edge of SYNC acts as an interrupt and the write
sequence is ignored by the DAC7512.
