X9315WPI-2.7

Digital Potentiometers Overview

The X9315WPI-2.7 is a digitally controlled potentiometer (XDCP) from the Renesas X9315 series, manufactured by Intersil/Renesas. It features a single potentiometer with 32 taps and a resistance of 10 kOhms. The device utilizes a linear taper and nonvolatile memory to retain wiper position data. It operates on a serial 3-wire interface (CS, U/D, INC) and supports supply voltages between 2.7 V and 5.5 V. The component is housed in an 8-pin SOIC package and is designed for surface mount installation.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as specifications may vary by production batch. Check for End-of-Life (EOL) notices or obsolescence warnings prior to procurement planning.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise digital adjustment of analog resistance values without mechanical wear. Ensure the 10 kOhm resistance and 32-tap resolution meet circuit requirements. Verify that the 3-wire serial interface is compatible with the host microcontroller's available GPIO pins.

Digital Potentiometers Part Context

This component belongs to the X9315 family of low-noise, low-power digitally controlled potentiometers. It serves as a solid-state replacement for traditional mechanical potentiometers in space-constrained PCB designs where reliability and programmability are critical.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9315 variants such as X9315WSZ-2.7 or X9315TMIZ for pin-compatible alternatives with different resistance values or packaging options.
