Digital Potentiometers

MCP4661-103E/ST Description

The MCP4661-103E/ST from Microchip Technology is a dual-channel, 10kΩ digital potentiometer with 257 taps, offering precise resistance adjustment via an I2C interface. Designed for surface-mount applications, it operates within a 1.8V to 5.5V supply range, making it suitable for low-voltage systems. This IC integrates linear taper functionality with a ±20% tolerance and a 150ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Its 75Ω typical wiper resistance minimizes signal distortion, while selectable address and mute features enhance flexibility in multi-device configurations. Packaged in a 14-TSSOP tube, it complies with ROHS3 and REACH standards, meeting stringent environmental regulations.
