X9315TM-2.7

Digital Potentiometers Overview

The X9315TM-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 100 kOhms. The device utilizes a nonvolatile memory to store wiper positions, which are recalled upon power-up. Control is managed via a 3-wire serial interface (CS, U/D, INC). It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in an MSOP-8 package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position after power loss
• 3-wire serial control interface (CS, U/D, INC)
• Single potentiometer with 32 resistive taps
• 100 kOhm total resistance with linear taper

Digital Potentiometers Applications

• Audio volume control circuits
• Variable gain amplifier adjustment
• Calibration of sensor signals
• Programmable bias voltage generation

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific suffix variations for packaging or temperature ratings. Check for end-of-life notices or obsolescence warnings prior to procurement planning.

Digital Potentiometers Selection Notes

Select this component when a high-resistance digital potentiometer with nonvolatile storage is required. Ensure the 100 kOhm value fits the circuit impedance requirements. Verify that the MSOP-8 package dimensions are compatible with the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the X9315 family of low-noise, low-power digitally controlled potentiometers. The 'TM' suffix typically indicates the MSOP-8 package variant, while '-2.7' denotes the minimum operating voltage capability. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance.

Digital Potentiometers Replacement Considerations

Compatible substitutes include other X9315 variants with different resistance values (e.g., X9315UM-2.7 for 50k) or packages (e.g., X9315WSZ for SOIC-8). Cross-reference pinouts and electrical specifications carefully before substitution.
