OPI125 Datasheet Optically Coupled Isolator

Manufacturer: TT Electronics

Overview: OPI125, OPI126, OPI128.

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.

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.
