X9C103P

Overview

The X9C103P is a non-volatile digital potentiometer manufactured by Renesas Electronics (formerly Intersil/Xicor). It features a single potentiometer with 100 tap points and a total resistance of 10 kOhms. The device utilizes a 3-wire serial interface for control and stores wiper positions in non-volatile memory, allowing recall upon power-up. Operating on a single 5V supply, it draws 750 uA in standby. The component is housed in an 8-pin PDIP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Non-volatile memory retains wiper position after power loss
• 100-tap resolution with linear taper
• 3-wire serial control interface
• Low power CMOS technology

Applications

• Digitally controlled resistance trimming
• Volume control in audio circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference setting

Procurement Notes

Verify the specific suffix 'P' against manufacturer documentation to confirm the package type, as variations exist within the X9C103 family. Confirm availability status, as this component may be subject to discontinuation or limited stock depending on the current production cycle.

Selection Notes

Select the X9C103P when a through-hole 8-pin DIP package is required for a 10kOhm non-volatile digital potentiometer. Ensure the application voltage does not exceed the maximum terminal voltage limits and that the 3-wire serial interface is compatible with the host controller.

Part Context

This part belongs to the X9C10 series of solid-state non-volatile potentiometers. It serves as a direct replacement for traditional mechanical potentiometers in applications requiring programmable resistance values without moving parts.

Replacement Considerations

Check for suffix variations such as 'SZ' (SOIC-8) or 'PM' (PDIP-8 with different interface) to ensure pinout and package compatibility before substitution.
