Low-side current sensing
For accurate and high-bandwidth current measurement
Precision low-side current measurement amplifiers for industrial and automotive applications
Low-side current sensing is a widely adopted technique for measuring the current flowing through a load. It involves placing a sensing resistor between the load and the ground. This method is favored for its simplicity and effectiveness and is used in various applications. By measuring the voltage drop across the sensing resistor, the current can be precisely determined.
