X9315WMZT1

Digital Potentiometers Overview

The X9315WMZT1 is a single-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features a 10 kOhm resistance value with 32 taps and a linear taper. The device utilizes a nonvolatile memory to retain wiper position data across power cycles. It operates on a serial 3-wire interface (CS, U/D, INC) for control. The unit is housed in an MSOP-8 surface-mount package and supports a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 50 uA.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up
• Serial 3-wire interface for simplified control
• Linear taper with 32 discrete tap positions
• Low power consumption with 50 uA operating current

Digital Potentiometers Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• System calibration settings

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm RoHS compliance status via official datasheets. Check moisture sensitivity level (MSL 2) requirements for storage and handling. Ensure packaging matches reel specifications for automated assembly processes.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise 10 kOhm resistance adjustment with persistent settings. Compare against X9315WSZT1 if SOIC-8 packaging is preferred over MSOP-8. Verify that the 3-wire interface compatibility exists with the host microcontroller. Ensure supply voltage constraints align with the 4.5 V to 5.5 V operational range.

Digital Potentiometers Part Context

This component belongs to the X9315 family of digitally controlled potentiometers. It shares core functionality with variants like X9315UMIZT1 but differs in resistance value and package type. The X9315 series is designed for low-noise, low-power applications requiring reliable, nonvolatile resistance adjustment without mechanical wear.

Digital Potentiometers Replacement Considerations

X9315WSZT1 offers identical electrical specifications in an SOIC-8 package. X9315UMIZT1 provides a 50 kOhm variant in MSOP-8. Verify pinout compatibility and thermal characteristics when substituting packages.
