INA203AID TI Current Sense Amplifier | 14-SOIC | 80V Common-Mode, 1.2MHz Bandwidth

Product Overview

The INA203AID is a high-side current-sense amplifier from Texas Instruments, designed for precise current measurement in systems with common-mode voltages up to 80V. It features a voltage output that is proportional to the sensed current, with a gain of 100 V/V. The device operates from a single 2.7V to 18V supply and is specified over the extended industrial temperature range of -40°C to +125°C. Housed in a 14-pin SOIC package, the INA203AID integrates a precision shunt resistor and provides a high-accuracy, low-drift solution for current monitoring in a variety of applications.
