Working Principles

The MCP4532-103E/MS utilizes a combination of digital control and resistive elements to provide variable resistance. It consists of a resistor array, wiper switches, and control logic. The digital inputs control the position of the wiper, which determines the effective resistance between the A and B terminals.

When a specific resistance value is set digitally, the MCP4532-103E/MS adjusts the wiper position accordingly, changing the resistance seen by the external circuit. The non-volatile memory ensures that the resistance setting is retained even when power is disconnected.
