INA200AIDGKT Texas Instruments, Current Sense Amplifier 8-Pin MSOP

Current and power measurement for real-time system protection, feedback control and high-accuracy system monitoring.

The Texas Instruments INA200, INA201, and INA202 devices are high-side current-shunt monitors with voltage output and integrated comparator. The INA20x devices can sense drops across shunts at common-mode voltages from –16 V to 80 V. The INA20x series is available with three output voltage scales: 20V/V, 50 V/V, and 100 V/V, with a bandwidth up to 500-kHz.

Current Sensing Amplifiers have a voltage output that is proportional to the volt drop across a very low value resistor, usually in a high-current power rail. Hence they measure the current flowing in that power rail.
