FOD2741C - Optically Isolated Error Amplifier

Download the FOD2741C datasheet PDF. This datasheet also covers the FOD2741A variant, as both devices belong to the same optically isolated error amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

The FOD2741 Optically Isolated Amplifier consists of the popular KA431 precision programmable shunt reference and an optocoupler.

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

Features

  • Optocoupler, precision reference and error amplifier in single package.
  • 2.5V reference.
  • CTR 100% to 200%.
  • 5,000V RMS isolation.
  • UL approved E90700, Volume 2 CSA approval 1296837 VDE approval 40002463 BSI approval 8702, 8703.
  • Low temperature coefficient 50ppm/°C max.
  • FOD2741A: tolerance 0.5% FOD2741B: tolerance 1% FOD2741C: tolerance 2%.
