MCP4562-502E/MS

Digital Potentiometers Overview

The MCP4562-502E/MS is a single-channel digital rheostat manufactured by Microchip Technology. It features an 8-bit resolution providing 257 taps and utilizes nonvolatile EEPROM memory to retain wiper settings. The nominal resistance (R_AB) is 5 kΩ with a ±20% tolerance. It operates on a supply voltage range of 1.8V to 5.5V, drawing a typical inactive current of 2.5 µA. The device communicates via an I²C serial interface supporting standard, fast, and high-speed modes.

Digital Potentiometers Feature Summary

• Nonvolatile Memory: Retains wiper position after power loss using WiperLock™ technology.
• 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.
• Low Power: Typical inactive current is 2.5 µA.

Digital Potentiometers Applications

• Variable gain control in audio circuits
• Programmable biasing for analog sensors
• Calibration adjustment in industrial instrumentation

Digital Potentiometers Procurement Notes

Verify the specific suffix 'E/MS' corresponds to the MSOP-8 package and RoHS compliance. Confirm the '-502' code indicates the 5 kΩ resistance value. Ensure the ordering prefix matches the required tape-and-reel or tube packaging format for production integration.

Digital Potentiometers Selection Notes

Select this model for applications requiring a variable resistor configuration rather than a potentiometer. The 5 kΩ resistance is suitable for moderate current loads. Verify that the system logic levels are compatible with the I²C interface requirements across the intended operating voltage range.

Digital Potentiometers Part Context

This component belongs to the MCP456X family of single-channel digital potentiometers. Unlike volatile counterparts, it includes EEPROM storage. It shares the same pinout and interface protocols as other devices in the MCP454X/456X/464X/466X series, differing primarily in memory type and channel count.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include MCP4562T-502E/MS (tape and reel variant). Cross-family alternatives like MCP4542 offer similar functionality but lack nonvolatile memory retention capabilities.
