Additional Details
The MCP4431-503E/ST from Microchip Technology is a digital potentiometer featuring a 50k Ohm resistance spread across 129 taps, providing precision control in electronic circuits. This component includes four independent resistor networks and utilizes an I2C interface for communication, allowing for easy integration with microcontrollers and other digital systems. Housed in a 20-TSSOP package, the MCP4431-503E/ST offers a compact design suitable for space-constrained applications. It operates as a volatile device, meaning its settings reset upon power-off, and it features a linear taper with a tolerance of ±20%, ensuring consistent performance within specified parameters.
