MCP4652-104E/UN

MCP4652-104E/UN Description

The MCP4652-104E/UN from Microchip Technology is a dual-channel, 100kΩ 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 and portable electronics. This volatile-memory device features a linear taper and a ±20% tolerance, with a typical wiper resistance of 75Ω. Its 150ppm/°C temperature coefficient ensures stable performance across varying environmental conditions. Packaged in a 10MSOP tube, it is RoHS3 compliant and rated for MSL 2 (1 Year) moisture sensitivity.

MCP4652-104E/UN Features

• Dual-channel rheostat configuration for independent or synchronized resistance control.
• Selectable I2C addresses enable multi-device operation on a single bus.
• Mute function allows quick wiper reset to mid-scale, ideal for audio applications.
• Low wiper resistance (75Ω typ) minimizes signal distortion in precision circuits.
• Wide voltage range (1.8V–5.5V) supports battery-powered and mixed-voltage systems.
