MCP4152T-104E/MF

Digital Potentiometers Overview

The MCP4152T-104E/MF is a single-channel, 8-bit digital rheostat manufactured by Microchip Technology. It features a nominal end-to-end resistance (RAB) of 100 kΩ with a ±20% tolerance and provides 256 discrete tap positions for precise resistance adjustment. The device utilizes volatile RAM memory to store wiper settings, which are lost upon power loss. Communication is managed via a high-speed SPI serial interface supporting up to 10 MHz at VDD ≥ 2.7V. It operates within a supply voltage range of 1.8V to 5.5V and includes high-voltage tolerant digital inputs capable of withstanding up to 12.5V.

Digital Potentiometers Feature Summary

• Single-channel 8-bit digital rheostat with 100 kΩ nominal resistance and 256 taps.
• SPI serial interface operating at frequencies up to 10 MHz.
• High-voltage tolerant digital inputs rated up to 12.5V.
• Wide operating voltage range from 1.8V to 5.5V.

Digital Potentiometers Applications

• Variable gain control in instrumentation amplifiers
• Programmable bias current generation
• Digital potentiometer replacement in calibration circuits

Digital Potentiometers Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging and the 'MF' suffix denotes the DFN-8 package variant. Confirm the '104' code corresponds to the 100 kΩ resistance value. Ensure the specific revision matches the required electrical characteristics for your application.

Digital Potentiometers Selection Notes

Select this component when a single-channel variable resistor is needed with SPI control. The 100 kΩ value suits applications requiring higher impedance levels compared to the 5 kΩ or 10 kΩ options. The volatile memory requires external non-volatile storage if wiper position retention across power cycles is necessary.

Digital Potentiometers Part Context

This part belongs to the MCP41XX family of single-channel digital potentiometers. It shares the same core architecture as the MCP413X (7-bit) and MCP416X (non-volatile) variants but offers 8-bit resolution and volatile memory. The 'T' suffix specifically identifies the reel packaging format used for automated surface-mount assembly.

Digital Potentiometers Replacement Considerations

Direct functional replacements include other MCP4152 variants with different packages (e.g., MCP4152-104E/MS). Cross-family alternatives like the MCP4252 offer dual channels instead of single. Verify pinout compatibility and thermal performance when substituting between package types.
