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.
