Overview
The INA200AIDR is a high-side current-shunt monitor produced by Texas Instruments. It is part of the INA20x series, which includes the INA200, INA201, and INA202 devices. These devices are designed to sense drops across shunts at common-mode voltages ranging from –16 V to 80 V. The INA200AIDR features a voltage output and an integrated open-drain comparator, making it a comprehensive solution for current sensing applications. It operates from a single 2.7-V to 18-V supply and is available in SOIC-8 and VSSOP-8 packages, ensuring versatility and compactness.
