INA181A1IDBVR TI Special Purpose

The INA181A1IDBVR is a bidirectional, zero‑drift current‑sense amplifier from Texas Instruments, featuring a fixed gain of 20 V/V and a 350‑kHz bandwidth in a 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.
