TSC2020 - STMicroelectronics

TSC2020 bidirectional current sense amplifier

TSC2020, TSC2021 and TSC2022 are a series of precision bidirectional current sense amplifier. They can sense current via a shunt resistor over a wide range of common-mode voltages, from -4 to +100 V, whatever the supply voltage is. It is able to sense very low drop voltages, minimizing measurement error. TSC2020, TSC2021 and TSC2022 are current sense amplifi.
