The INA225AIDGKT is a voltage-output, Current Sense Amplifier, senses drops across current-sensing resistors at common-mode voltages that can vary from 0 to 36V, independent of the supply voltage. The device is a bidirectional, current-shunt monitor that allows an external reference to be used to measure current flowing in both directions across a current-sensing resistor. Four discrete gain levels are selectable using the two gain-select terminals (GS0 and GS1) to program gains of 25, 50, 100 and 200V/V. The low-offset, zero-drift architecture and precision gain values enable current-sensing with maximum drops across the shunt as low as 10mV of full-scale while maintaining very high accuracy measurements over the entire operating temperature range. The device operates from a single +2.7 to +36V power supply, drawing a maximum of 350µA of supply current.
