X9116WS8I-2.7

Digital Potentiometers Overview

The X9116WS8I-2.7 is a digitally controlled potentiometer (XDCP) manufactured by Xicor, a division of Intersil. It features a single circuit with 10 kΩ total resistance and 16 tap positions. The device utilizes an increment/decrement control interface (U/D, INC, CS) for wiper positioning. It operates on a supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a typical temperature coefficient of ±300 ppm/°C and a tolerance of ±20%. The component employs non-volatile memory to retain the last wiper position upon power-up.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile design with 16 programmable wiper taps
• 3-wire up/down serial interface for digital control
• Operates at VCC = 2.7V and 5V with low active current (max 50µA)
• Linear taper configuration in an 8-lead SOIC package

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring temperature stability
• Systems needing solid-state reliability over time

Digital Potentiometers Procurement Notes

Verify part status as obsolete or end-of-life through official Renesas or Intersil channels. Confirm RoHS compliance and specific packaging details such as tube or reel quantities. Check for alternate manufacturing sites or PCN notices affecting assembly or labeling before procurement.

Digital Potentiometers Selection Notes

Select this component when a 10 kΩ linear digital potentiometer with non-volatile storage is required. Ensure the application supports the 3-wire serial interface protocol. Verify that the operating voltage falls within the 2.7 V to 5.5 V range and that the ±20% tolerance meets circuit accuracy requirements.
