X9C103SI

Overview

The X9C103SI is a single-channel non-volatile digital potentiometer from the X9C10 series by Renesas Electronics. It features a 10 kΩ end-to-end resistance with linear taper and 100 tap points. The device utilizes a 3-wire serial interface (CS, U/D, INC) for control. It operates on a single 5V supply with a maximum active current of 3mA and standby current of 750µA. The wiper position is stored in EEPROM, allowing recall upon power-up. It is housed in an 8-pin SOIC package.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• 100-tap resolution with ±20% tolerance
• Low power CMOS technology (750µA standby)
• Simple 3-wire serial interface

Applications

• Digitally controlled resistance trimming
• Programmable voltage reference adjustment
• Audio volume control circuits
• Offset voltage error trimming in amplifiers

Procurement Notes

Verify the suffix 'I' indicates industrial temperature range (-40°C to +85°C). Confirm package type is SOIC-8. Check RoHS compliance status as per latest datasheet revision. Ensure ordering quantity matches tube packaging standards if applicable.

Selection Notes

Select X9C103SI for applications requiring 10kΩ resistance with non-volatile storage. Compare with X9C102 (1kΩ) or X9C104 (100kΩ) for different resistance needs. Consider X9110 for SPI interface or higher resolution requirements. Verify supply voltage compatibility with 5V systems.

Part Context

Part of the XDCP™ family. Shares architecture with X9C102, X9C103SZ, X9C104, and X9C503. Differentiated by resistance value (10kΩ) and package suffix (I for Industrial temp).

Replacement Considerations

X9C103SZ is a compatible variant with commercial temperature range. X9C102 and X9C104 offer same interface but different resistance values.
