MCP4021T-502E/SN Description

The MCP4021T-502E/SN from Microchip Technology is a 5kΩ digital potentiometer with 64 taps, designed for precision analog signal adjustment in surface-mount applications. Operating within a 2.7V to 5.5V supply range, this single-channel device features a linear taper and an Up/Down (U/D, CS) interface for straightforward digital control. With a ±20% resistance tolerance and a 150ppm/°C temperature coefficient, it ensures stable performance across varying environmental conditions. The 70Ω typical wiper resistance minimizes signal distortion, making it suitable for high-accuracy applications. Packaged in an 8-SOIC Tape & Reel (TR), it is RoHS3 compliant and rated MSL 1 (Unlimited) for moisture sensitivity, ensuring reliability in automated assembly processes.
