SMP9317
OVERVIEW
The SMP9317 DACPOT trimmer is a 7-bit nonvolatile
DAC designed to replace mechanical potentiometers.
The SMP9317 includes a unity-gain amplifier to buffer the
DAC output and enables V
OUT
to swing from rail to rail.
The DACPOT trimmer operates over a supply voltage
range of 2.7V to 5.5V.
The SMP9317’s simple up/down counter input provides
an ideal interface for automatic test equipment to dither
and monitor the V
OUT
voltage. This interface allows for
quick and consistent calibration of even the most sophis-
ticated systems.
The SMP9317 is a pin-compatible performance upgrade
for other industry nonvolatile potentiometers. The
SMP9317 offers higher resolution than these devices and
provides ‘clickless’ transitions of V
OUT
.
