STEVAL-ISQ014V1, Low-Side Current Sensing Evaluation Board based on TSZ121 Op Amp
STEVAL-ISQ014V1, Evaluation Board implements a low-side current sensing which consists in placing a sense resistor between the load and the circuit ground. The resulting voltage drop is amplified using TSZ121 op amp. The common mode voltage is close to ground, whatever the voltage of the power source, so the current sense voltage can be amplified by this low voltage op amp without restriction. The circuit offers very stable electrical characteristics over the entire supply voltage range and is particularly suited for automotive and industrial applications
