Overview
The INA196AIDBVTG4 is a high-precision current shunt monitor produced by Texas Instruments. This device is part of the INA19xA-Q1 family, which is designed to sense voltage drops across shunts at common-mode voltages ranging from -16 V to 80 V. The INA196AIDBVTG4 operates from a single 2.7-V to 18-V power supply and is specified over an extended operating temperature range of -40°C to 125°C. It is packaged in a compact SOT-23 (5) package, measuring 2.90 mm × 1.60 mm, making it suitable for space-constrained applications.
