STMicroelectronics TSC199 Low/High Side Bidirectional Amplifiers

STMicroelectronics TSC199 Low/High Side Bidirectional Amplifiers are designed to sense current through a shunt resistor over a wide range of common-mode voltages from -0.3V to +26V. The TSC199 is supplied in three different versions, each with a different gain: 50V/V, 100V/V, and 200V/V.

The STMicroelectronics TSC199 Amplifiers were developed with a specific zero-drift architecture, which can perform at high precision. The device can sense very low drop voltages, as low as 10mV full scale, decreasing measurement error. The TSC199 may be used in various operations such as precision current measurement, overcurrent protection, current monitoring, and feedback loops.

The TSC199 entirely operates over the expansive supply voltage range of 2.7V to 26V and the industrial temperature range of -40°C to 125°C.
