When disabled, the output goes to a high impedance state and the supply current draw is reduced to less than 0.5 µA. The INA190 is intended for use in either low-side and high-side current-sensing configurations where high accuracy and low current consumption are required. The INA190 is a specially-designed, current-sensing amplifier that accurately measure voltages developed across current-sensing resistors on common-mode voltages that far exceed the supply voltage. Current can be measured on input voltage rails as high as 40 V, with a supply voltage as low as 1.7 V. 7.2 Functional Block Diagram |
