Product Overview

LT®1999 is a high speed and voltage precision bidirectional current sense amplifier, designed to monitor bidirectional currents over a wide common mode range. It senses current via an external resistive shunt and generates an output voltage, indicating both magnitude and direction of the sensed current. This output voltage is referenced halfway between the supply voltage and ground or an external voltage can be used to set the reference level. 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. A shutdown mode is provided for minimizing power consumption. Applications are high side or low side current sensing, H-bridge motor control, solenoid current sense, high voltage data acquisition, PWM control loops, fuse/MOSFET monitoring.
  • Operates from an independent 5V supply and draws 1.55mA
  • Gain accuracy of 0.5% maximum
  • AC CMRR 80dB at 100KHz
  • Input offset voltage of 1.5mV maximum
  • Bandwidth of 2MHz
  • Smooth, continuous operation over entire common mode range
  • 4KV HBM tolerant and 1KV CDM tolerant
  • Low power shutdown 10µA
  • 8-lead plastic MSOP package, 0°C to 70°C temperature range
