MCP4023T-103E/CH

Overview

The MCP4023T-103E/CH is a nonvolatile, 6-bit digital potentiometer manufactured by Microchip Technology. It features 64 taps and utilizes the WiperLock™ technology to store wiper settings in EEPROM without requiring an external write-protect pin. The device operates on a simple Up/Down (U/D) serial interface with high-voltage tolerant inputs up to 12.5V. Electrical specifications include a supply voltage range of 2.7V to 5.5V, a typical wiper resistance of 75Ω, and low power consumption with a maximum static current of 1µA. It supports linear taper configurations and is available in the SOT-23-6 package.

Feature Summary

• Nonvolatile memory with WiperLock™ technology for secure setting retention
• High-voltage tolerant digital inputs supporting up to 12.5V
• Simple Up/Down (U/D) serial control interface
• Low power operation with 1µA maximum static current

Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Sensor calibration systems

Procurement Notes

Verify the specific suffix 'CH' against the manufacturer's official documentation to confirm the exact package type and tape/reel specifications. Ensure that the ordering information matches the required temperature grade and packaging format before finalizing procurement orders.

Selection Notes

Select this component when a nonvolatile digital potentiometer with a simple two-wire control interface is required. The MCP4023T-103E/CH is suitable for applications needing high-voltage tolerance on control lines and power-on recall of resistance values without additional logic components.

Part Context

This part belongs to the MCP4021/2/3/4 family of low-cost nonvolatile digital potentiometers. While sharing core electrical characteristics and WiperLock™ technology, the MCP4023 variant specifically designates the Potentiometer configuration within the SOT-23-6 package form factor.

Replacement Considerations

Direct replacements within the same family include MCP4021T-103E/CH and MCP4022T-103E/CH. Verify pin compatibility and configuration mode (Potentiometer vs. Rheostat) when substituting.
