Working Principle

With a wiper resistance range of 32179Ω and 10-bit resolution, the MCP4432T-103E/ST is a very precise digital potentiometer. It works by taking the control voltage from the external power supply and adjusting the total resistance by changing the position of the wiper. When the control voltage changes, the position of the wiper also moves, thereby adjusting the resistance value. The MCP4432T-103E/ST also has a non-volatile memory and is programmable, allowing users to configure the wiper\'s position as desired.

The MCP4432T-103E/ST also features both a potentiometer specification and an operational amplifier specification. In the potentiometer configuration, it has two external pins, which are connected to the resistor terminals and the wiper terminal. In the operational amplifier configuration, it has four pins with two external pins connected to the resistor terminals and two pins connected to the operational amplifier.

Closing Thoughts

The MCP4432T-103E/ST is a powerful digital potentiometer. With its non-volatile memory and programmable wiper position, it enables users to precisely control the output voltage of a voltage-divider network, making it an ideal choice for a wide range of data acquisition applications.
