INA284AID TI Current Sense Amplifier | 8-SOIC | 2.7V-18V, 1.1MHz

Product Overview

The INA284AID is a high-accuracy, bidirectional current sense amplifier from Texas Instruments, designed for precision current measurement in a wide range of applications. It operates over a common-mode voltage range from -14V to +80V, independent of the supply voltage, making it ideal for high-side and low-side sensing. The device features a gain of 100 V/V and a bandwidth of 1.1 MHz, enabling fast response times. Housed in an 8-pin SOIC package, it offers a compact solution for space-constrained designs.
