MCP4562T-104E/MF

Digital Potentiometers Overview

The MCP4562T-104E/MF is a single-channel digital potentiometer IC from Microchip Technology, featuring nonvolatile memory and an I²C serial interface. It provides 8-bit resolution with 257 discrete taps and a nominal resistance (R_AB) of 100 kΩ. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, supporting operation down to 1.8V. Key electrical parameters include a typical wiper resistance of 75 Ω, a temperature coefficient of 150 ppm/°C over the extended range (-40°C to +125°C), and a bandwidth of 100 kHz at 8-bit resolution. It utilizes a DFN-8 EP package.

Digital Potentiometers Feature Summary

• Nonvolatile Memory: Stores wiper settings in EEPROM with WiperLock™ technology for security.
• I²C Interface: Supports Standard (100 kHz), Fast (400 kHz), and High-Speed (3.4 MHz) modes.
• High-Voltage Inputs: Digital inputs tolerate up to 12.5V, allowing compatibility with higher voltage logic.
• Terminal Control: Includes a TCON register for resistor network terminal disconnect features.

Digital Potentiometers Applications

• Calibration systems requiring persistent setting retention.
• Audio volume control and tone adjustment circuits.
• Programmable gain amplifiers and sensor signal conditioning.
• Industrial process control instrumentation.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'MF' corresponds to the DFN-8 EP package with exposed thermal pad as documented in the datasheet. Confirm that the 'T' indicates tape and reel packaging if required by assembly equipment. Ensure the design accounts for the high-voltage tolerant inputs when interfacing with logic levels exceeding VDD.

Digital Potentiometers Selection Notes

Select this model for applications requiring a rheostat configuration with 100 kΩ total resistance and nonvolatile storage. Compare against volatile variants like the MCP4552 if power-down retention is unnecessary. Consider the DFN-8 EP package for thermal management advantages over MSOP options. Verify I²C bus speed requirements against the device's support for up to 3.4 MHz.

Digital Potentiometers Part Context

This component belongs to the MCP45XX family of single-channel digital potentiometers. It shares architectural similarities with the MCP46XX series but differs in channel count and pinout configurations. The '62' designation specifically identifies it as an 8-bit nonvolatile rheostat variant within the broader MCP454X/456X/464X/466X product line.
