OVERVIEW
The SMP9517 DACPOT trimmer is an 7-bit nonvolatile
DAC designed to replace mechanical potentiometers.
The SMP9517 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 SMP9517’s simple pushbutton input provides an ideal
interface for operator adjusted equipment. This interface
allows for quick and easy adjustment of even the most
sophisticated systems.
The SMP9517 is a pin-compatible performance upgrade
for other industry nonvolatile potentiometers. For higher
resolution applications the pin-compatible S9518 pro-
vides 256 steps with the same pushbutton interface. Both
the SMP9517 and the S9518 provide ‘clickless’ transitions
of V
