MCP4562T-503E/MF

Digital Potentiometers Overview

The MCP4562T-503E/MF is a single-channel digital rheostat manufactured by Microchip Technology. It features an 8-bit resolution providing 257 taps and utilizes nonvolatile memory to retain wiper settings. The nominal resistance between terminals A and B is 50 kΩ with a ±20% tolerance. The device operates on a supply voltage range of 2.7V to 5.5V, with serial interface functionality available down to 1.8V. It communicates via an I²C interface supporting standard, fast, and high-speed modes. The component is housed in a DFN 3x3 (MF) package.

Digital Potentiometers Feature Summary

• Nonvolatile Memory: Retains wiper settings automatically upon power-up using EEPROM.
• I²C Interface: Supports 100 kHz, 400 kHz, and up to 3.4 MHz operation.
• High-Voltage Inputs: Digital inputs tolerate voltages up to 12.5V.
• WiperLock™ Technology: Allows calibration settings to be secured in the EEPROM.

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Sensor biasing

Digital Potentiometers Procurement Notes

Verify the specific suffix 'MF' corresponds to the DFN 3x3 package with an exposed thermal pad. Confirm that the 'T' indicates tape and reel packaging if required for automated assembly. Ensure the operating environment stays within the -40°C to +125°C temperature range specified for this device.

Digital Potentiometers Selection Notes

Select this model when a single rheostat configuration with 50 kΩ resistance is needed. The 8-bit resolution provides 257 steps for precise control. Choose this part over volatile variants (MCP4552) if power-down retention of the resistance value is required without external battery backup.

Digital Potentiometers Part Context

This component belongs to the MCP45XX family of single resistor network digital potentiometers. It shares the same core architecture as the MCP4561 but is configured specifically as a rheostat rather than a potentiometer. It is part of the broader MCP454X/456X/464X/466X series which includes dual-channel options.

Digital Potentiometers Replacement Considerations

The MCP4562T-503E/MS is a pin-compatible alternative in an MSOP-8 package. For dual-channel applications, the MCP4662T-503E/MF offers two independent rheostats in a larger footprint.
