OPI125 - OPTICALLY COUPLED ISOLATOR

General Description

Each OPI125, OPI126, and OPI128 consists of an optically coupled isolator with a gallium arsenide infrared emitting diode coupled to a monolithic integrated circuit.

This circuit incorporates a photodiode, a linear amplifier and a Schmitt trigger on a single silicon chip.

Key Features

  • Multiple output options.
  • 15 kV dc input-to-output isolation voltage.
  • Direct TTL/STTL interface.
  • High noise immunity.
  • Data rates to 250 KBit/s.
  • Hermetically sealed.
  • TX-TXV process available.
  • UL File No. E 58730.

OPI125, OPI126, OPI128 Features:  Multiple output options  15 kV dc input-to-output isolation voltage  Direct TTL/STTL interface  High noise immunity  Data rates to 250 KBit/s  Hermetically sealed  TX-TXV process available  UL File No. E 58730* Description: Each OPI125, OPI126, and OPI128 consists of an optically coupled isolator with a gallium arsenide infrared emitting diode coupled to a monolithic integrated circuit. This circuit incorporates a photodiode, a linear amplifier and a Schmitt trigger on a single silicon chip. For maximum long-term stability, both the diode and the Photologic® sensor are hermetically sealed in separate packages and then mounted in a high dielectric plastic housing.
