MCP4241T-502E/ML

Digital Potentiometers Overview

The MCP4241T-502E/ML is a dual-channel digital potentiometer IC from Microchip Technology, featuring non-volatile memory and WiperLock™ technology. It provides two independent potentiometer networks with 7-bit resolution (129 steps) and a nominal resistance of 5 kΩ. The device operates on an SPI serial interface supporting up to 10 MHz at VDD ≥ 2.7V. Key electrical characteristics include a typical wiper resistance of 75 Ω, a bandwidth of 2 MHz for the 5 kΩ variant, and an operating voltage range of 2.7V to 5.5V for full device specifications. It supports high-voltage tolerant digital inputs up to 12.5V.

Digital Potentiometers Feature Summary

• Dual Potentiometer Configuration: Two independent 7-bit resistor networks with 129 positions each.
• Non-Volatile Memory: EEPROM storage retains wiper settings across power cycles; includes WiperLock™ for security.
• SPI Interface: High-speed serial communication up to 10 MHz with modes 0,0 and 1,1 support.
• High Voltage Tolerance: Digital input pins (CS, SCK, SDI, WP, SHDN) tolerate voltages up to 12.5V.

Digital Potentiometers Applications

• Audio volume control and tone adjustment circuits
• Programmable gain amplifiers and variable attenuators
• Voltage reference trimming and calibration systems
• Industrial process control parameter adjustment

Digital Potentiometers Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet DS22059B. Confirm that the 'T' suffix indicates tape and reel packaging if required by assembly equipment. Ensure compatibility with the system's SPI clock speed and voltage levels before integration.

Digital Potentiometers Selection Notes

Select this model for applications requiring dual independent analog resistance control with persistent state retention. The 5 kΩ value suits moderate current loads. For single-channel needs, consider the MCP4141 series. For higher resolution, the MCP4261 offers 8-bit (257 steps). Verify thermal dissipation requirements for the ML (MSOP) package in high-temperature environments.

Digital Potentiometers Part Context

This component belongs to the MCP414X/416X/424X/426X family of SPI digital potentiometers. The '41' designation indicates a dual potentiometer configuration with non-volatile memory. The '-502' suffix specifies the 5 kΩ resistance value. The '/ML' suffix denotes the 8-lead MSOP package type.

Digital Potentiometers Replacement Considerations

Direct functional substitutes within the same family include MCP4241-502E/ML (tray packaging) or MCP4241-502E/P (PDIP). For pin-compatible upgrades with higher resolution, the MCP4261-502E series is available. Ensure any replacement maintains the 7-bit resolution and non-volatile memory requirement.
