MCP4261T-104E/ML

Digital Potentiometers Overview

The MCP4261T-104E/ML is a dual-channel, 8-bit non-volatile digital potentiometer manufactured by Microchip Technology. It features two independent resistor networks with 257 taps and a nominal resistance (R_AB) of 100 kΩ. The device operates on a single supply voltage ranging from 2.7V to 5.5V and utilizes a high-speed SPI serial interface for communication. Key specifications include a typical wiper resistance of 75 Ω, an extended operating temperature range of -40°C to +125°C, and WiperLock™ technology for secure calibration settings stored in EEPROM.

Digital Potentiometers Feature Summary

• Dual 8-bit Non-Volatile Digital Potentiometers with 257 taps
• 100 kΩ Nominal Resistance (R_AB)
• SPI Serial Interface supporting up to 10 MHz
• WiperLock™ Technology for EEPROM security

Digital Potentiometers Applications

• Embedded systems requiring durable, vibration-resistant resistance adjustment
• Power management modules needing programmable gain or bias settings
• Sensor signal conditioning circuits with automated calibration
• Audio equipment utilizing digital volume or tone control

Digital Potentiometers Procurement Notes

Verify the specific package suffix 'ML' corresponds to the 16-pin QFN form factor during sourcing. Confirm that the 'T' designation indicates tape-and-reel packaging if reel quantity is required for assembly. Ensure the component meets RoHS compliance standards as specified in the manufacturer documentation.

Digital Potentiometers Selection Notes

Select this model when dual-channel analog control is necessary within a compact footprint. The 100 kΩ resistance value is suitable for low-current applications but may require consideration of leakage currents in high-impedance circuits. Verify that the host microcontroller supports the required SPI modes (0,0 or 1,1) and voltage levels compatible with the 2.7V–5.5V operating range.

Digital Potentiometers Part Context

This component belongs to the MCP41XX/MCP42XX family of digital potentiometers. The 'MCP4261' base part number identifies it as a dual-channel, 8-bit device with non-volatile memory. The '-104E' suffix denotes the 100 kΩ resistance value and industrial temperature grade, while '/ML' specifies the QFN package type.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements within the same family include the MCP4261 without the 'T' prefix for tube packaging. For single-channel requirements, the MCP4161 offers identical electrical characteristics in a reduced pin count. Cross-family substitutes like the MCP4361 provide quad-channel functionality but differ in pinout and package dimensions.
