The STMicroelectronics TSC2010, TSC2011 and TSC2012 are precision bidirectional current sense amplifiers. They can sense the current thanks to a shunt resistor over a wide range of common mode voltages, from - 20 to + 70 V, whatever the supply voltage is.

Wide common mode voltage: - 20 to 70 V
Offset voltage: ± 200 μV max
2.7 to 5.5 V supply voltage
Gain error: 0.3% max
Offset drift: 5 μV/°C max
Quiescent current: 20 μA in shutdown mode
