MCP4152-103E/SN

MCP4152-103E/SN Description

The MCP4152-103E/SN from Microchip Technology is a 10kΩ digital potentiometer configured as a rheostat, offering 257 taps for precise resistance adjustment. Designed for surface-mount applications, it operates over a 1.8V to 5.5V supply range, making it suitable for low-voltage systems. The device features an SPI interface for digital control, ensuring seamless integration with microcontrollers and other digital systems. With a ±20% tolerance and a 150ppm/°C temperature coefficient, it balances performance and stability. The volatile memory requires reconfiguration upon power-up, while the 75Ω typical wiper resistance minimizes signal distortion. Packaged in an 8-SOIC tube, it is ROHS3 compliant and REACH unaffected, meeting environmental standards.
