The LT1999 high-voltage amplifier from Linear Technology is designed for bidirectional current sensing in the presence of fast-switching common-mode voltages from -5 to +80 V. This wide-input common-mode range is obtained with standard low-voltage op amp supplies. A 2 MHz bandwidth enables the device to monitor currents in H-bridge motor controls, switching power supplies, solenoids, and battery chargers. To maintain high accuracy, even when monitoring motor and solenoid current, the unit guarantees more than 80 dB of common-mode rejection at 100 kHz. This ensures insensitivity to large square-wave-input common-mode voltages.
