X9116WS8Z-2.7T1

Digital Potentiometers Overview

The X9116WS8Z-2.7T1 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, formerly Intersil. It features a single potentiometer with 10 kΩ end-to-end resistance and 16 wiper taps. The device operates on a supply voltage range of 2.7 V to 5.5 V and consumes a maximum active current of 150 µA. It utilizes a 3-wire serial interface for control and includes nonvolatile memory to retain the last wiper position upon power-up. The component is housed in an 8-lead SOIC package and is rated for operation between 0°C and +70°C.

Digital Potentiometers Feature Summary

• Solid-state nonvolatile 16-tap digital potentiometer with 10 kΩ resistance
• 3-wire up/down serial interface for tap position programming
• Power-on recall of stored wiper position from nonvolatile memory
• Operates on 2.7 V to 5.5 V supply with low standby current

Digital Potentiometers Applications

• Trimmer applications replacing mechanical potentiometers
• Variable resistance circuits requiring temperature stability
• Parameter adjustment in solid-state systems

Digital Potentiometers Procurement Notes

This component is classified as obsolete or discontinued by the manufacturer. Verification of availability should focus on distributor surplus stock or secondary market sources, as standard manufacturing channels no longer support new production orders.

Digital Potentiometers Selection Notes

Select this part for single-potentiometer applications requiring 16 discrete resistance steps. Ensure the system interface supports the 3-wire serial protocol (INC, U/D, CS). Verify that the 10 kΩ resistance value and ±20% tolerance align with circuit requirements.

Digital Potentiometers Part Context

The X9116 belongs to the XDCP family of digitally controlled potentiometers. This specific suffix indicates an 8-lead SOIC package with a -2.7V minimum operating voltage rating and tape-and-reel packaging. It serves as a solid-state alternative to mechanical trimmers in consumer and industrial electronics.

Digital Potentiometers Replacement Considerations

Direct replacements may be limited due to the obsolete status. Consider checking for pin-compatible variants within the same X9116 series or evaluating newer generation digital potentiometers with similar tap counts and interface protocols.
