DESCRIPTION
It is available with a preset gain of 20 V/V. Thanks to its high precision, it can sense very low drop voltages, minimizing measurement error. The TSC240 is a current sense amplifier that can be used in various functions such as precision current measurement, overcurrent protection, current monitoring, and feedback loops. These devices fully operate over the broad supply voltage range of 2.7 to 5.5 V and over the industrial temperature range of -40 to +125 °C.
