概述

Description

The MCP41050-I/SN is a digital potentiometer manufactured by Microchip Technology. It features a 256-position, non-volatile, single-channel variable resistor that can be controlled via a SPI (Serial Peripheral Interface) interface. The device is designed for applications where precise resistance adjustment is needed, such as in audio equipment, sensor calibration, and signal processing.
Key features include a maximum supply voltage of 5.5V, low power consumption, and the ability to store settings even when powered off due to its EEPROM technology. The MCP41050 has a linear taper and offers a resistance value of 50 kΩ, making it suitable for a wide range of electronic applications.
Its compact package (usually in a 14-pin TSSOP) allows for easy integration into space-constrained designs. Overall, the MCP41050-I/SN is an efficient solution for electronic volume control, gain adjustment, and other tasks requiring adjustable resistance in digital circuits.

Features
