Overview
The INA198AIDBVT from Texas Instruments is a high-performance current sense amplifier designed for a wide range of applications. This device is part of the INA193-INA198 family of current shunt monitors, which are capable of sensing voltage drops across shunts at common-mode voltages from -16 V to +80 V. The INA198 operates from a single supply voltage of 2.7 V to 18 V and is housed in a compact SOT-23 (DBV) package with 5 pins. It is optimized for use in current control loops with a bandwidth of up to 500 kHz.
