X9315WSIZ-2.7T1

Digital Potentiometers Overview

The X9315WSIZ-2.7T1 is a digitally controlled potentiometer (XDCP) from Renesas Electronics, part of the XDCP series. It features a single circuit with 32 taps and a resistance value of 10 kOhms. The device utilizes nonvolatile memory to retain wiper position settings across power cycles. It operates on a serial 3-wire interface (U/D, INC, CS) for control. The component supports supply voltages ranging from 2.7V to 5.5V and is housed in an 8-SOIC surface-mount package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up
• 3-wire serial interface (CS, U/D, INC)
• Linear taper with 32 tap positions
• Single circuit configuration

Digital Potentiometers Applications

• Volume control in audio systems
• Gain adjustment in instrumentation circuits
• Voltage reference trimming
• Sensor calibration

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as datasheets indicate variations between standard and -2.7 suffix versions. Confirm package type matches design requirements, as the base model may appear in SOIC or MSOP formats depending on the specific suffix. Check for obsolescence notices via manufacturer PCNs before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when a low-power, nonvolatile digital potentiometer is required. Ensure the 10k resistance value fits the application's impedance constraints. Verify that the 3-wire interface is compatible with the host microcontroller's available pins. Consider the operating temperature range (-40°C to +85°C) against environmental conditions.

Digital Potentiometers Part Context

This part belongs to the Intersil/Renesas X9315 family of low-noise, low-power digitized potentiometers. The 'Z' suffix typically denotes RoHS compliance, while '-2.7' indicates support for lower voltage operation starting at 2.7V. The 'T1' suffix specifies tape-and-reel packaging for automated assembly.
