Overview
The INA200AIDGKTG4 is a high-side measurement current-shunt monitor produced by Texas Instruments. This device is part of the INA200 series, which includes the INA200, INA201, and INA202. It is designed to measure current across shunts at high common-mode voltages, making it suitable for a variety of applications requiring precise current monitoring.
The INA200AIDGKTG4 features an integrated comparator and provides a voltage output proportional to the measured current. It operates from a single supply voltage ranging from 2.7 V to 18 V and is available in compact VSSOP-8 and SOIC-8 packages.
