INA180A2IDBVR Bidirectional Current Sense Amplifier
TheINA180A2IDBVR is a low-voltage, bidirectional current sense amplifier from Texas Instruments, specifically designed for precise current measurement across a shunt resistor in a wide range of power management and monitoring applications. This device can accurately amplify a small differential voltage generated by current flow in either direction (from supply to load or from load to supply), making it ideal for systems with regenerative power flow like motor drives and battery charging circuits. It operates from a single power supply as low as 2.7V up to 5.5V, enabling its use in both low-voltage and standard 3.3V/5V systems.
This current sense amplifier features a fixed gain of 20 V/V (A2 version), with other variants offering gains of 50, 100, and 200 V/V. It supports common-mode voltage ranges from -0.2V to +26V, independent of the supply voltage, allowing it to monitor high-side or low-side current on rails higher than its own supply. Key specifications include a low input offset voltage (max 500 µV) and offset drift (2 µV/°C) to ensure accuracy over temperature. It offers a bandwidth of 350 kHz and a low quiescent current of 260 µA. Packaged in a small SOT-23-5 package, it is designed for space-constrained applications.
