DESCRIPTION
The DAC7617 is a quad, serial input, 12-bit, voltage
output Digital-to-Analog Converter (DAC) with guar-
anteed 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 zero-
scale (000H), selectable via the RESETSEL pin. The
individual DAC inputs are double buffered to allow
APPLICATIONS
q PROCESS CONTROL
q ATE PIN ELECTRONICS
q CLOSED-LOOP SERVO-CONTROL
q MOTOR CONTROL
q DATA ACQUISITION SYSTEMS
q DAC-PER-PIN PROGRAMMERS
for simultaneous update of all DAC outputs. The
device is powered from a single +3V supply.
Low power and small size makes the DAC7617 ideal
for automatic test equipment, DAC-per-pin program-
mers, data acquisition systems, and closed-loop servo-
control. The device is available in SO-16 and
SSOP-20 packages and is guaranteed over the
–40°C to +85°C temperature range.

NOTES: (1) Specification applies at code 00AH and above. (2) LSB means Least Significant Bit, with VREFH equal to +1.25V and VREFL equal to 0V, one LSB
is 0.305mV. (3) All DAC outputs will match within the specified error band. (4) Ideal output voltage does not take into account zero or full-scale error.
