X9317TM8-2.7

Digital Potentiometers Overview

The X9317TM8-2.7 is a digitally controlled potentiometer (XDCP) manufactured by Intersil, now part of Renesas Electronics. It features a single resistive element with a total resistance of 50 kOhms and provides 100 discrete wiper taps for precise adjustment. The device utilizes non-volatile memory to retain the wiper position upon power loss. It operates on a serial three-wire interface for control. The component supports a supply voltage range from 2.7 V to 5.5 V and draws a typical operating current of 50 uA. It is housed in an MSOP-8 surface-mount package and is rated for commercial temperature operation between 0°C and +70°C.

Digital Potentiometers Feature Summary
