Description

The TSC240 is a high-precision current sense amplifier with enhanced PWM

rejection. It can sense current via a shunt resistor over a wide range of common-

mode voltages, from -4 to +100 V, regardless of the supply voltage. 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.
