INA271AQDRZF TI Current Sense Amplifier | 110dB CMRR, 1.3MHz BW

Product Overview

The INA271AQDRZF is a high-side current sense amplifier from Texas Instruments, designed for precise current measurement in a wide range of applications. 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 offers excellent common-mode rejection ratio (CMRR) of 110dB (min) and bandwidth of 1.3MHz. Housed in a small SOIC-8 package, it is ideal for space-constrained designs.
