A power operational amplifier that provides on-the-fly adjustable current limit for flexibility and load protection in high current applications is described.
automatic test equipment
Many power operational amplifiers offer a built-in current limit where the limit is fixed or programmable through an external resistor. This offers the most basic measure of protection for the load circuitry, and the amplifier itself, under fault conditions. Sometimes, though, there is a need for on-the-fly current limiting to satisfy the requirements ...
