Overview
The INA194AIDBVR is a high-performance current sense amplifier produced by Texas Instruments. It is part of the INA193-INA198 family of current shunt monitors, designed to sense voltage drops across shunts at common-mode voltages ranging from -16 V to +80 V. This device operates from a single 2.7-V to 18-V supply and is available in a compact SOT-23 (DBV) package with 5 pins. The INA194AIDBVR is ideal for applications requiring precise current measurement and control, particularly in environments with high common-mode voltages.
