The LT1999IMS8-10#PBF is a high speed precision Current Sense Amplifier, designed to monitor bidirectional currents over a wide common mode range. This 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, this is suitable for monitoring currents in H-bridge motor controls, switching power supplies, solenoid currents and battery charge currents from full charge to depletion. It operates from an independent 5V supply and draws 1.55mA. A shutdown mode is provided for minimizing power consumption.
