X9315WMIZ-2.7T1R5419

Digital Potentiometers Overview

The X9315WMIZ-2.7T1R5419 is a single-channel digitally controlled potentiometer (XDCP) from the Renesas X9315 series, manufactured by Intersil/Renesas. It features a 10 kΩ end-to-end resistance with a linear taper and 32 discrete taps for precise resistance adjustment. The device utilizes a nonvolatile memory architecture to retain wiper position settings during power-off, automatically recalling them upon power-up. It operates on a serial 3-wire interface (CS, U/D, INC) for control and functions within a supply voltage range of 2.7 V to 5.5 V. The component is housed in an 8-lead MSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile Memory: Stores wiper position data for recall after power cycles.
• 3-Wire Serial Interface: Controlled via CS, U/D, and INC pins.
• Linear Taper: Provides uniform resistance steps across 32 taps.
• Low Power Consumption: Typical operating current of 50 µA.

Digital Potentiometers Applications

• Digitally controlled resistance trimming in signal processing circuits.
• Parameter adjustments in industrial instrumentation.
• Volume or gain control in audio equipment.
• Voltage reference adjustment in power supply systems.

Digital Potentiometers Procurement Notes

Verify the suffix 'R5419' against official Renesas documentation to confirm specific reel packaging or lot traceability details. Ensure compatibility with the 2.7V minimum supply voltage requirement for the system design. Check RoHS compliance status as indicated in the manufacturer's latest datasheet revision.

Digital Potentiometers Selection Notes

Select this component when a nonvolatile digital potentiometer with 10 kΩ resistance and linear characteristics is required. The MSOP-8 package is suitable for space-constrained PCB layouts. Ensure the application voltage does not exceed 5.5 V and that the control logic supports the 3-wire serial protocol.

Digital Potentiometers Part Context

This part belongs to the X9315 family of CMOS EEPOTs. Variants differ primarily in resistance values (e.g., 10k, 50k), taper types (linear/logarithmic), and package styles (MSOP/SOIC). The 'WMIZ' designation typically indicates the MSOP package and specific resistance/taper configuration.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9315 variants with matching 10 kΩ linear resistance and MSOP-8 packaging, such as X9315WMZ or X9315UMZ, provided the supply voltage and interface requirements are met. Verify pinout compatibility before substitution.
