Working Principles

The X9241AMVI operates by digitally controlling the resistance value between the H (high) and L (low) terminals. The W (wiper) terminal acts as a variable tap on the resistor network, allowing the user to select the desired resistance level. The digital control interface, consisting of CS, SCLK, and SDI pins, enables the user to send commands to adjust the resistance value. The non-volatile memory ensures that the resistance settings are retained even when power is disconnected.
