X9C104S

Overview

The X9C104S is a single-channel non-volatile digital potentiometer from the X9C10 series manufactured by Renesas Electronics. It features a 100 kΩ end-to-end resistance with a linear taper and 100 resistive taps. The device utilizes a three-wire serial interface (CS, U/D, INC) for wiper position control. It operates on a single 5V supply voltage within a commercial temperature range of 0°C to 70°C. The component integrates EEPROM to store wiper settings, ensuring data retention upon power cycling.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• Three-wire serial interface for simplified control
• 100 tap resolution with linear resistance taper
• Single channel configuration in an 8-pin SOIC package

Applications

• Programmable gain adjustment in signal processing circuits
• Volume control in audio equipment
• Offset voltage trimming in amplifier circuits
• Parameter adjustment in industrial control systems

Procurement Notes

Verify the specific suffix of the part number during procurement. Datasheets indicate that the 'SZ' suffix denotes a lead-free RoHS-compliant variant. Confirming the exact suffix ensures compatibility with environmental regulations and soldering processes required for the assembly line.

Selection Notes

Select this component when a simple serial interface is preferred over SPI or I2C protocols. The 100 kΩ resistance value suits applications requiring moderate impedance levels. Ensure the design accommodates the 5V supply requirement and the ±20% resistance tolerance specified for the resistor array.

Part Context

This component belongs to the XDCP family of digitally controlled potentiometers. It shares architectural similarities with the X9C102 and X9C103 models, differing primarily in total resistance values. The device replaces mechanical potentiometers in applications requiring programmable resistance without moving parts.

Replacement Considerations

The X9C104ST1 is identified as a discontinued version of this component. The X9C104SZT1 is listed as a direct replacement option for tape-and-reel packaging requirements.
