TSC199 is a series of zero-drift current sense amplifiers that can sense current via a shunt resistor over a wide range of common-mode voltages from -0.3 V to +26 V, whatever the supply voltage is. It is available in three different versions, each of them having a different gain: 50 V/V, 100 V/V, and 200 V/V. TSC199 is designed with a specific zero-drift architecture, which can achieve high precision. TSC199 is able to sense very low drop voltages, as low as 10 mV full scale, minimizing measurement error.

TSC199 are current sense amplifiers that may be used in various functions like precision current measurement, overcurrent protection, current monitoring, and feedback loops.

This device fully operates over the broad supply voltage range of 2.7 V to 26 V and over the industrial temperature range of -40 °C to 125 °C.
