X9C103S

Overview

The X9C103S is a single-channel, non-volatile digital potentiometer from the X9C10 series by Renesas Electronics. It features a 10 kΩ linear resistance taper with 100 wiper tap points and a ±20% tolerance. The device operates on a single 5V supply (4.5V to 5.5V range) and utilizes a 3-wire serial interface (CS, U/D, INC) for control. Key electrical parameters include a maximum active current of 3mA and standby current of 750µA at 5V. The component is housed in an 8-pin SOIC package.

Feature Summary

• Non-volatile memory stores wiper position for recall upon power-up
• 100-tap resolution with 99 temperature-compensated resistive elements
• Low-power CMOS technology with 750µA standby current
• High reliability rated for 100,000 data changes per bit

Applications

• Programmable gain adjustment in voltage amplifier circuits
• Volume control in audio signal processing applications
• Offset voltage trimming in operational amplifier circuits
• Parameter adjustment for variable DC reference voltages

Procurement Notes

Verify the specific suffix (e.g., SIZ, SZ, SZT1) against the required operating temperature range and packaging format. Industrial grade variants typically support -40°C to +85°C, while commercial grades may be limited to 0°C to +70°C. Confirm lead times as production cycles can extend beyond standard estimates due to market demand fluctuations.

Selection Notes

Select based on the required resistance value (10kΩ), taper type (linear), and interface compatibility (3-wire serial). Ensure the supply voltage matches the 5V requirement. Consider the package size (SOIC-8) constraints and verify if the industrial or commercial temperature rating meets the application environment specifications.

Part Context

The X9C103S belongs to the XDCP™ family of digitally controlled potentiometers manufactured by Renesas Electronics (formerly Intersil). This series integrates resistor arrays, wiper switches, and non-volatile memory into a single CMOS IC, replacing mechanical potentiometers in solid-state designs.

Replacement Considerations

Compatible substitutes within the same family include X9C102 (5kΩ), X9C104 (100kΩ), and X9C503 (10kΩ). These components share identical pinouts and control interfaces but differ in end-to-end resistance values.
