X9C303S8IZT1

Overview

The X9C303S8IZT1 is a digital potentiometer from the XDCP™ series, manufactured by Renesas Electronics Corporation. It features a single potentiometer circuit with 100 taps and a total resistance of 32 kΩ. The device operates on a ±5V power supply with a resistance tolerance of ±15% and a temperature coefficient of ±400ppm/°C. It utilizes non-volatile memory to retain settings and interfaces via Up/Down (U/D), INC, and CS pins. Packaged in an 8-SOIC format, it supports surface mount installation and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• 100-tap resolution with 32 kΩ total resistance
• Simple serial interface using U/D, INC, and CS signals
• Logarithmic taper characteristic for audio or control applications

Applications

• Volume control circuits
• Gain adjustment in signal conditioning
• Calibration of analog sensors

Procurement Notes

Verify component status as the X9C303S8IZT1 is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Check for RoHS compliance and moisture sensitivity level (MSL 1) before procurement. Ensure compatibility with existing PCB footprints for 8-SOIC packages.

Selection Notes

Select this component when a compact, digitally adjustable resistor is required without external mechanical parts. Verify that the 32 kΩ resistance range and ±15% tolerance meet circuit requirements. Consider the logarithmic taper if linear response is not needed. Ensure the system voltage aligns with the ±5V operating specification.

Part Context

This part belongs to the XDCP™ series of digital potentiometers. It combines the functionality of a traditional potentiometer with digital control capabilities. The S8I suffix indicates an 8-pin SOIC package variant. It is designed for applications requiring remote adjustment of resistance values in electronic systems.

Replacement Considerations

As the X9C303S8IZT1 is obsolete, consult Renesas documentation for direct replacements or cross-reference with similar digital potentiometers offering 100 taps and 32 kΩ resistance in an 8-SOIC package. Verify pinout compatibility and electrical specifications before substitution.
