X9315UMZ-2.7T1

Digital Potentiometers Overview

The X9315UMZ-2.7T1 is a digitally controlled potentiometer (XDCP) from the XDCP series, manufactured by Renesas Electronics Corporation. It features a single potentiometer circuit with 32 taps and a resistance of 50 kOhms. The device utilizes a linear taper and operates on a serial 3-wire interface (U/D, INC, CS). It supports supply voltages between 2.7 V and 5.5 V, with a typical operating current of 50 uA. The wiper position is stored in nonvolatile memory for retention across power cycles. It is housed in an 8-MSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position upon power-up
• 3-wire serial control interface (CS, U/D, INC)
• Linear taper with 32 resistive taps
• Single channel, 50 kOhm total resistance

Digital Potentiometers Applications

• Volume control in audio systems
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Programmable biasing circuits

Digital Potentiometers Procurement Notes

Verify component status as the X9315UMZ-2.7T1 is listed as obsolete or end-of-life by the manufacturer. Check distributor availability for remaining stock or alternative sourcing channels. Confirm RoHS compliance details, as some variants may differ. Ensure packaging specifications match requirements, typically supplied in tape and reel format.

Digital Potentiometers Selection Notes

Select this component when a nonvolatile digital potentiometer with 32 steps is required. Verify that the 50 kOhm resistance value fits the application's impedance constraints. Ensure the 2.7 V to 5.5 V supply range matches the system voltage. The 8-MSOP package size must fit the PCB layout. Consider the ±20% tolerance and ±300 ppm/°C temperature coefficient for precision requirements.

Digital Potentiometers Part Context

This part belongs to the X9315 family of low-power, 32-tap digitally controlled potentiometers. Other variants include different resistance values (e.g., 10 kOhm, 100 kOhm) and package types (SOIC, MSOP). The 'UMZ' suffix indicates the 8-MSOP package, while '2.7T1' denotes the 2.7 V minimum supply voltage rating and tape-and-reel packaging.

Digital Potentiometers Replacement Considerations

Direct replacements are limited due to the obsolete status. Consider checking for newer generations from Renesas or compatible parts from other manufacturers offering similar 32-tap, nonvolatile digital potentiometers with 3-wire interfaces. Verify pin compatibility and electrical parameters before substitution.
