• Low Power, 1mW max at +5V
OVERVIEW
The S9318 DACPOT™ trimmer is an 8-bit nonvolatile
DAC designed to replace mechanical potentiometers.
The S9318 includes a unity-gain amplifier to buffer the
DAC output and enables VOUT to swing from rail to rail.
The DACPOT trimmer operates over a supply voltage
range of 2.7V to 5.5V.
The S9318’s simple up/down counter input provides an
ideal interface for automatic test equipment to dither and
monitor the VOUT voltage. This interface allows for quick
and consistent calibration of even the most sophisticated
systems.
The S9318 is a pin-compatible performance upgrade for
other industry nonvolatile potentiometers. The S9318
offers double the resolution of these devices and provides
‘clickless’ transitions of VOUT.
