STMicroelectronics STEVAL-AETKT2V1 Evaluation Kit utilizes the bidirectional TSC21x Current Sense Amplifiers by placing a sense resistor either in the high or low side. The STEVAL-AETKT2V1 Kit includes a motherboard and two different daughter boards for different gain configurations.
The STM TSC21x Current Sense Amplifiers are designed to sense current via a shunt resistor over a wide range of common-mode voltages, from -0.3V to +26V. This low/high side, bidirectional current sense amplifier is designed with a specific zero-drift architecture, enabling high precision. The TSC21x offers an extremely precise gain and very high CMRR performance via thin-film resistors. Additionally, the TSC21x can be used as a unidirectional or bidirectional current sensing amplifier by fixing the output common-mode voltage through a reference pin.
