The TSC2012IYDT is a high-voltage, precision bidirectional current sense amplifier from STMicroelectronics. It is designed to measure small currents over a wide range of input voltages, from 0 to 40V, with a very high accuracy of 0.25% over temperature. It offers two modes of operation: SENSE mode, intended to measure DC and AC inputs up to 500kHz, and LIMIT mode for limiting the output current. For both modes, the amplifier can be configured for unidirectional or bidirectional sensing. The TSC2012IYDT also features high common-mode noise rejection, wide power supply range and low power consumption. This integrated circuit is designed for automotive, industrial as well as healthcare system applications.
