X9C104SIT2

Overview

The X9C104SIT2 is a digitally controlled potentiometer from the X9C10 series by Renesas Electronics. It features a single channel with a resistance value of 100 kΩ and a linear taper. The device includes 100 taps for precise adjustment and utilizes non-volatile memory to retain wiper position data across power cycles. It operates on a 5 V supply voltage and communicates via a serial 3-wire interface. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Retains programmed wiper position through non-volatile memory upon power cycling
• Adjustable resistance via simple three-wire control interface
• Linear taper configuration for uniform resistance distribution

Applications

• Signal processing parameter adjustment
• Control system variable resistance
• Electronic volume or gain control

Procurement Notes

Verify the specific suffix 'IT2' against official Renesas documentation, as standard listings typically use 'SZ' or 'ST'. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering code matches the required temperature range and packaging format for your production needs.

Selection Notes

Select this component when a non-volatile digital potentiometer with 100 kΩ resistance is required. The 3-wire interface simplifies microcontroller connections compared to I2C or SPI alternatives. Verify that the 5 V operating voltage aligns with your system's power rails and that the SOIC-8 footprint fits your PCB layout constraints.

Part Context

This part belongs to the X9C10 series of EEPROM-based digital potentiometers. These devices integrate a resistor array, wiper switching network, and control logic into a single CMOS IC. The series is designed to replace mechanical potentiometers in applications requiring remote adjustment or automated calibration without manual intervention.

Replacement Considerations

Direct substitutes include X9C104SZT1 and X9C104ST1. Cross-brand equivalents such as DS1804Z-100+ may be considered if pin compatibility and interface protocols are verified.
