Analog Devices (MAX44284HAUT+T) Current Sense Amplifier, High Precision

Current Sense Amplifier, High Precision, 1 Amplifier, 2000 pA, SOT-23, 6 Pins, -40 °C, 125 °C

Product Overview
The MAX44284HAUT+T is a 36V, input common-mode, high precision, low power current-sense amplifier in 6 pin SOT-23 package. It is a high-side, current-sense amplifier that operates with a 1.7V to 5.5V single supply and is optimized for very low power operation with only 21µA of quiescent current. The MAX44284 is ideal for many battery-powered, handheld devices because it uses only maximum 31.2µA quiescent supply current to extend battery life. The device’s low input offset voltage, tight gain error and low temperature drift characteristics allow the use of small-sense resistors for current measurements to improve power-supply conversion efficiency and accuracy of measurements. This feature allows monitoring of power-supply load current even if the rail is shorted to ground. High-side current monitoring does not interfere with the ground path of the load being measured, making the IC particularly useful in a wide range of high-reliability systems.
