MCP4152-503E/MF

Digital Potentiometers Overview

The MCP4152-503E/MF is an 8-bit single rheostat digital potentiometer manufactured by Microchip Technology. It features a 10 kΩ nominal resistance (R_AB) with 257 discrete steps and volatile memory. The device operates on a supply voltage of 1.8V to 5.5V, utilizing a high-speed SPI serial interface capable of up to 10 MHz. Key electrical characteristics include a typical wiper resistance of 75 Ω and a bandwidth of 2 MHz for the 5 kΩ variant. It supports split-rail applications and includes high-voltage tolerant digital inputs up to 12.5V.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'MF' corresponds to the DFN package type as indicated in official documentation. Confirm that the 'E' designation aligns with the extended industrial temperature range specifications (-40°C to +125°C). Ensure compatibility with the required SPI mode settings before integration.

Digital Potentiometers Selection Notes

Select this component when an 8-bit resolution rheostat configuration is required. The 10 kΩ resistance value suits moderate current applications. Verify that the system utilizes an SPI interface compatible with modes 0,0 or 1,1. Note that the device retains volatile memory, requiring wiper settings to be reloaded after power cycles.

Digital Potentiometers Part Context

This part belongs to the MCP413X/415X/423X/425X family of digital potentiometers. These devices offer single or dual resistor network options with either 7-bit or 8-bit resolutions. The family supports both potentiometer and rheostat configurations via pinout flexibility.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include other MCP415x variants with different resistance values or packages. Cross-family substitution requires verifying SPI compatibility and voltage tolerance levels.
