MCP4023T-502E/CH

Overview

The MCP4023T-502E/CH is a nonvolatile, 6-bit digital potentiometer manufactured by Microchip Technology. It features a nominal resistance of 5 kΩ with 64 taps and utilizes WiperLock™ technology to store the wiper setting in EEPROM. The device operates on a single supply voltage ranging from 2.7V to 5.5V and supports an extended temperature range of –40°C to +125°C. Control is managed via a simple Up/Down (U/D) serial interface, allowing for high-voltage tolerant inputs up to 12.5V. It is housed in a compact SOT-23-6 package.

Feature Summary

• Nonvolatile memory with WiperLock™ technology for power-on recall of settings
• Simple Up/Down (U/D) serial control interface
• High-voltage tolerant digital inputs up to 12.5V
• Low static current consumption of 1 µA maximum

Applications

• Audio volume control circuits
• Variable gain amplifier adjustment
• Sensor calibration and offset trimming
• Voltage reference level shifting

Procurement Notes

Verify the specific ordering suffix 'CH' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the full part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a nonvolatile digital potentiometer with a 5 kΩ resistance value is required. The U/D interface is suitable for systems with limited I/O pins. Consider the 64-tap resolution and ±20% resistance tolerance. Verify that the 12.5V input tolerance matches the control logic levels used in the application design.

Part Context

This part belongs to the MCP4021/2/3/4 family of low-cost nonvolatile digital potentiometers. The MCP4023 variant specifically uses a 6-pin SOT-23 package and is configured as a potentiometer. Other family members include different pin counts or rheostat configurations.

Replacement Considerations

Direct replacements within the same family include MCP4023T-202E/CH (2.1 kΩ), MCP4023T-103E/CH (10 kΩ), and MCP4023T-503E/CH (50 kΩ). These share identical pinouts and control protocols but differ in total resistance values.
