MAX9919NASA+T: Precision Uni-/Bidirectional Current-Sense Amplifier, 90V/V Gain, -20V to +75V Input Range
The MAX9919NASA+T is a high-accuracy, single-supply current-sense amplifier designed for monitoring current in inductive loads such as motors and solenoids. It features a wide input common-mode range of -20V to +75V, which is independent of the supply voltage, allowing it to handle inductive kickback and reverse-battery conditions. This specific 'N' version provides a fixed gain of 90V/V. The device supports both unidirectional and bidirectional current sensing using an external reference voltage. It operates from a single 4.5V to 5.5V supply and is fully specified over the automotive temperature range.
Temp Range-40 to +125°C
