INA303A2QPWRQ1 TI Current Sense Amplifier | 14-TSSOP | 0-36V, 1.5MHz

Product Overview

The INA303A2QPWRQ1 is a high-voltage, bidirectional, zero-drift current sense amplifier from Texas Instruments, designed for automotive and industrial applications. It features a wide common-mode voltage range from 0V to 36V, independent of the supply voltage, and operates from a single 2.7V to 5.5V supply. The device provides an analog output voltage proportional to the sensed current, with a gain of 100V/V. It is qualified to AEC-Q100 for automotive applications.
