Working Principles

The X9241AYVT2 utilizes a combination of digital logic and non-volatile memory to provide programmable resistance. When a resistance value is programmed, it is stored in the non-volatile memory, allowing the IC to retain the setting even when power is removed. The programmed resistance can be adjusted using the serial interface, providing precise control over the resistance level.
