DESCRIPTION
The DAC7614 is a quad, serial input, 12-bit, voltage
output digital-to-analog converter (DAC) with guaranteed 12-bit monotonic performance over the –40°C
to +85°C temperature range. An asynchronous reset
clears all registers to either mid-scale (800H) or zeroscale (000H), selectable via the RESETSEL pin. The
device can be powered from a single +5V supply or
from dual +5V and –5V supplies.

Low power and small size makes the DAC7614 ideal
for process control, data acquisition systems, and
closed-loop servo-control. The device is available in
16-pin plastic DIP, 16-lead SOIC, or 20-lead SSOP
packages, and is guaranteed over the –40°C to +85°C
temperature range.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
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.
