The STEVAL-AETKT1V2 evaluation kit represents a bidirectional current sense amplifier with high side or low side sense resistor. The kit consists of a main board and individual daughter boards for the TSC2011, TSC2010 and TSC2012 high voltage, bidirectional, current sense amplifier ICs, which provide a a fixed gain of 60, 20 or 100, respectively.
The thin film resistor on the TSC201x devices ensure extremely precise gain and very high common-mode rejection ratio (CMRR) performance, even in high frequency ranges. They accurately measure current by amplifying the voltage (VSENSE) across a shunt resistor connected to the input. Moreover, the ability to fix the output common mode voltage means that the device can be either used as unidirectional or bidirectional current sensing amplifier.
