MCP4261T-103E/ML

MCP4261T-103E/ML Description

The MCP4261T-103E/ML from Microchip Technology is a dual-channel digital potentiometer (digipot) with a 10kΩ resistance and 257 taps, offering precise analog adjustment via SPI interface. Designed for surface-mount applications, it operates within a 1.8V to 5.5V supply range, making it suitable for low-voltage systems. The device features a linear taper and a ±20% tolerance, ensuring consistent performance across industrial and consumer applications. Its WiperLock™ technology enhances reliability by preventing unintended wiper movement, while the 150ppm/°C temperature coefficient ensures stability in varying thermal conditions. Packaged in a 16-QFN (Tape & Reel), it complies with ROHS3 and REACH standards.

MCP4261T-103E/ML Features

• Dual-channel configuration: Two independent potentiometers in one IC.
• High resolution: 257 taps for fine-grained adjustment.
• Low wiper resistance: 75Ω (typical) minimizes signal distortion.
