MCP4011T-503E/MS

Overview

The MCP4011T-503E/MS is a volatile, 6-bit digital potentiometer manufactured by Microchip Technology. It features a 50 kΩ resistance value with 64 taps and operates within a supply voltage range of 1.8V to 5.5V. The device utilizes a simple Up/Down (U/D) serial interface for wiper control and includes power-on recall of default settings. It supports linear taper configurations and offers low temperature coefficients of 50 ppm/°C absolute and 10 ppm/°C ratiometric. The component is housed in an 8-pin MSOP package and functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• 6-bit resolution providing 64 discrete tap positions
• High-voltage tolerant digital inputs up to 12.5V
• Low static current consumption of 1 µA maximum
• Wide operating voltage range from 1.8V to 5.5V

Applications

• Volume control circuits
• Gain adjustment stages
• Voltage reference trimming
• Sensor biasing networks

Procurement Notes

Verify the specific suffix 'MS' corresponds to the 8-lead MSOP package configuration. Confirm the 'E' designation indicates compliance with RoHS standards and absence of halogenated materials. Ensure the 'T' prefix matches the required reel packaging format for automated assembly processes.

Selection Notes

Select this model when a volatile memory type is acceptable for wiper position retention. The U/D interface requires only two control lines, simplifying microcontroller GPIO usage compared to SPI or I2C alternatives. Verify that the 50 kΩ resistance value aligns with the target circuit impedance requirements.

Part Context

This component belongs to the MCP4011/2/3/4 family of low-cost digital potentiometers. While other variants in the series offer rheostat configurations or different pinouts, the MCP4011 specifically provides a potentiometer configuration. The T-503E/MS designation specifies the tape-and-reel packaging, 50 kΩ resistance, extended temperature grade, and MSOP package style.

Replacement Considerations

Direct replacements include other MCP4011 variants with different resistance values or packages, such as MCP4011-103E/MS for 10 kΩ applications. Cross-family substitutes like the MCP41xxx series require interface adaptation due to differing control protocols.
