Overview

Description

The INA196AIDBVR is a high-speed, precision current-shunt monitor from Texas Instruments, designed for use in various applications requiring current measurement. It operates on a single power supply, typically ranging from 2.7V to 18V, and offers a fixed gain of 20 V/V. Its primary function is to amplify small differential voltages across a shunt resistor, allowing for accurate current sensing while rejecting common-mode voltages.
This device is suitable for bidirectional current sensing applications due to its capability to handle common-mode voltages from -16V to +80V. The INA196AIDBVR provides high accuracy with low offset voltage and low input bias current, making it ideal for precision applications. Additionally, it features a wide operating temperature range from -40°C to +125°C, making it versatile for industrial and automotive environments.
With a small SOT-23 package, the INA196AIDBVR is suitable for space-constrained designs. It is commonly used in power management systems, battery chargers, and motor control systems, where real-time current monitoring is crucial.
