X9C303S8Z

Overview

The X9C303S8Z is a nonvolatile digital potentiometer manufactured by Renesas Electronics Corporation. It features a single circuit with 100 taps and a total resistance of 32 kΩ. The device utilizes an increment/decrement control interface (U/D, INC, CS) for wiper position adjustment. It operates on a 5V supply voltage and is housed in an 8-SOIC surface-mount package. The component maintains its setting via internal nonvolatile memory and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Nonvolatile memory retains wiper position upon power loss
• 32 kΩ resistance value with 100 discrete tap positions
• Increment/Decrement serial control interface
• Single-channel configuration in 8-SOIC package

Applications

• Volume control in audio equipment
• Gain adjustment in signal conditioning circuits
• Voltage reference trimming
• Parameter adjustment in industrial instrumentation

Procurement Notes

Verify the specific suffix 'S8Z' against the official datasheet to confirm pinout compatibility and material compliance. Confirm current availability status as distribution channels may list obsolete or end-of-life variants. Ensure the source document explicitly identifies the manufacturer as Renesas Electronics Corporation to avoid confusion with legacy Intersil branding.

Selection Notes

Select this component when a 32 kΩ resistance value is required with nonvolatile storage capabilities. The 100-tap resolution provides sufficient granularity for most analog control applications. Verify that the 5V logic levels and incremental interface match the system controller's output signals. Ensure the operating environment remains within the specified 0°C to 70°C commercial temperature range.

Part Context

This part belongs to the X9C30 series of digitally controlled potentiometers. It shares architectural similarities with other members like the X9C302 and X9C304, differing primarily in resistance values. The SOIC-8 package allows for compact PCB layouts compared to through-hole alternatives. The series is designed for replacing mechanical potentiometers in applications requiring digital programmability.

Replacement Considerations

Check for direct substitutes such as the X9C302S8Z or X9C304S8Z if resistance tolerance differs. Verify pin-to-pin compatibility with other 8-pin digital potentiometers from different manufacturers before substitution.
