DESCRIPTION
The LT®1999 is a high speed precision current sense amplifier, designed to monitor bidirectional currents over a wide common mode range.

The LT1999 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. The LT1999 operates from an independent 5V supply and draws 1.55mA. A shutdown mode is provided for minimizing power consum
