Nonvolatile digital trimming potentiometer

Onlinecomponents.com, an authorized distributor of Honeywell, features the CLAROCHIP CC9317. The device is a nonvolatile digital trimmer. The device is a DAC designed to replace mechanical trimmers. The CLAROCHIP CC9317 includes a unity-gain amplifier to buffer the DAC output and enables VOUT to swing from rail to rail.

The trimmer operates over a supply voltage range of 2.7 V to 5.5 V. Its 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 CLAROCHIP CC9317 is a pin-compatible performance upgrade for other industry nonvolatile potentiometers. It offers higher resolution than these devices and provides “clickless” transitions of VOUT.
