X9116WS8-2.7

Digital Potentiometers Overview

The X9116WS8-2.7 is a digitally controlled potentiometer (XDCP) manufactured by Xicor, a division of Intersil. It features a single potentiometer with 10 kΩ total resistance and 16 tap positions. The device utilizes an increment/decrement control interface requiring three pins: Up/Down (U/D), Increment (INC), and Chip Select (CS). It operates on a supply voltage range of 2.7 V to 5.5 V. The component includes non-volatile memory to retain the wiper position during power cycles. It is housed in an 8-pin SOIC package.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile design with 16 programmable wiper taps
• 3-wire up/down serial interface for tap position control
• Non-volatile memory retains last wiper position at power-up
• Linear taper with ±20% resistance tolerance

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring digital adjustment
• Systems needing temperature and time stability over mechanical components

Digital Potentiometers Procurement Notes

Verify component status as obsolete or end-of-life through official manufacturer channels. Confirm RoHS compliance and specific packaging details such as tube or reel quantities. Check for alternate manufacturing sites or PCN notices regarding assembly changes. Ensure compatibility with existing board layouts for the 8-SOIC package.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with 16 steps is required. Verify that the system supports the 3-wire increment/decrement interface rather than I2C or SPI. Ensure the operating voltage falls within the 2.7 V to 5.5 V range. Consider the linear taper characteristic for applications requiring uniform resistance change per step.

Digital Potentiometers Part Context

This part belongs to the X9116 series of Digitally Controlled Potentiometers originally from Xicor, which was acquired by Intersil and later became part of Renesas Electronics. The 'WS8' suffix indicates the 8-lead SOIC package variant. The '-2.7' denotes the minimum operating voltage capability.
