TSC103IYPT

Instrumentation, Op Amps, Buffer Amps Overview

The TSC103IYPT is a high-side current sense amplifier from STMicroelectronics, designed to measure differential voltages across shunt resistors in high-voltage environments. It translates these measurements into ground-referenced output signals. The device operates with a supply voltage range of 2.7 V to 5.5 V and supports a wide common-mode voltage range from 2.9 V to 70 V. Key electrical parameters include a maximum quiescent current of 360 µA, an input offset voltage of 500 µV, and a common-mode rejection ratio of 105 dB. It features a 700 kHz bandwidth, a slew rate of 0.6 V/µs, and selectable gains of 20, 25, 50, or 100 V/V. The component is housed in an 8-TSSOP package and is qualified under AEC-Q100 standards for automotive applications.
