Current Sensing Amplifiers

Current sensing amplifiers measure current by outputting a voltage that is proportional to the flowing power current. A resistor is used to convert the load current to a small voltage which is then accurately amplified. They offer real-time overcurrent protection.

What are the different applications of current sensing amplifiers?

Accurate current sensing is crucial to optimising p...
