STMICROELECTRONICS STEVAL-AETKT4V1 Evaluation Board, TSC2020, TSC2021, TSC2022, Precision, Bidirectional Current Sense Amplifier

STEVAL-AETKT4V1 is an evaluation kit for TSC202x family, high voltage, precision current sense amplifier. This evaluation kit implements bidirectional current sense amplifiers. It consists of a motherboard and three different daughter boards for different gain configurations. The STEVAL-AET041V1B is a mother board, which can accept different daughter boards to use different gain configuration. STEVAL-AET042V1B: daughter board with a TSC2020 mounted with a gain of 20. STEVAL-AET043V1B: daughter board with a TSC2021 mounted with a gain of 50. STEVAL-AET044V1B: daughter board with a TSC2022 mounted with a gain of 100. The TSC202x family is a current sense amplifier specifically designed to accurately measure current by amplifying the voltage across a shunt resistor connected to its input. It features a zero-drift topology, allowing it to achieve a high CMRR of at least 100dB and a low input-offset voltage of 200µV at a common mode voltage of 12V and over temperature.
