X9C103SIZ

Overview

The X9C103SIZ is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics. It features a 10 kΩ end-to-end resistance with a linear taper and 100 tap points. The device utilizes a non-volatile memory to store wiper positions, ensuring data retention upon power-up. It operates on a single 5 V supply (4.5 V to 5.5 V range) with a typical standby current of 750 µA. The component uses a three-wire serial interface for control and is housed in an 8-SOIC package.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• Three-wire serial interface (CS, U/D, INC)
• 100 tap points with ±20% resistance tolerance
• Low power CMOS technology (750 µA standby)

Applications

• Digitally controlled resistance trimming
• Signal processing parameter adjustment
• Volume or gain control in audio circuits

Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range (-40°C to +85°C). Confirm packaging type (Tube vs. Tape & Reel) matches assembly requirements. Check RoHS compliance status as per latest datasheet revisions. Ensure pinout compatibility if replacing legacy Intersil parts.

Selection Notes

Select this model for applications requiring precise 10 kΩ resistance adjustment without mechanical wear. Compare with X9C102 (1 kΩ) or X9C104 (100 kΩ) if different resistance values are needed. Verify that the 3-wire interface aligns with the host microcontroller's available GPIO pins.

Part Context

Part of the X9C10x family of solid-state potentiometers. Shares core architecture with X9C102, X9C104, and X9C503. Manufactured under Renesas Electronics following the acquisition of Intersil. Commonly used in industrial and consumer electronics for calibration tasks.

Replacement Considerations

X9C103SZT1: Same electrical specifications but packaged in tape and reel instead of tube. X9C103SI: Similar variant; verify temperature range and packaging differences against design constraints.
