INA181A2IDBVR TI Special Purpose

The INA181A2IDBVR is a bidirectional, zero‑drift current‑sense amplifier from Texas Instruments, featuring a fixed gain of 50 V/V and a 210‑kHz bandwidth in a compact SOT‑23‑6 package . It operates from a 2.7‑V to 5.5‑V supply, senses common‑mode voltages from –0.2 V to +26 V, and draws only 260 µA of quiescent current . For selection, verify the common‑mode range includes your bus voltage, ensure the supply voltage is within 2.7 V–5.5 V, note the gain error of ±1% (max) and offset voltage of ±150 µV at VCM = 0 V . The device operates from –40 °C to +125 °C and supports bidirectional sensing, making it suitable for motor control, battery monitoring, power management, overcurrent detection, solar inverters, and lighting control .
