FOD2712A - Optically Isolated Error Amplifier

General Description

The FOD2712A Optically Isolated Amplifier consists of the popular AZ431L precision programmable shunt reference and an optocoupler.

The optocoupler is a gallium arsenide (GaAs) light emitting diode optically coupled to a silicon phototransistor.

The reference voltage tolerance is 1%.

Key Features

  • Optocoupler, precision reference and error amplifier in single package.
  • 1.240V ± 1% reference.
  • CTR 100% to 200%.
  • 2,500V RMS isolation.
  • UL approval E90700.
