Working Principles

The MAX5700AUB+T is a voltage-to-current converter IC that operates by converting an input voltage signal into a corresponding output current. It achieves this through an internal transconductance amplifier that converts the voltage at the IN+ and IN- terminals into a proportional current at the OUT terminal. The output current can be adjusted by connecting an external set resistor to the SET pin.
