LT1999HMS8-10#PBF, Current Sense Amplifiers Hi V, Bi-dir C Sense Amp
Semiconductors\Integrated Circuits - ICs\Amplifier ICs\Current Sense AmplifiersLT1999 Bidirectional Current Sense Amplifier
Analog Devices LT1999 Bidirectional Current Sense Amplifier is designed to monitor bidirectional currents over a wide common-mode range. The device is offered in three gain options (10V/V, 20V/V, and 50V/V). The LT1999 senses current via an external resistive shunt and generates an output voltage, indicating both magnitude and direction of the sensed current. The output voltage is referenced halfway between the supply voltage and ground, or an external voltage can be used to set the reference level. With a 2MHz bandwidth and a common-mode input range of -5V to 80V, the LT1999 is suitable for monitoring currents in H-Bridge motor controls, switching power supplies, solenoid currents, and battery charge currents from full charge to depletion.
