The STMicroelectronics TSC215 is a series of zerodrift current sense amplifiers that can sense current via a shunt resistor over a wide range of common mode voltages from -0.3 to +26 V, whatever the supply voltage is. They are available in three different versions, each of them having a different gain. The TSC21x are designed with a specific zero-drift architecture, which can achieve high precision.
