Description

The OPI155 contains a high speed

monolithic photo-IC comprised of a

photodiode and DC amplifier driving an

open collector output Schottky transistor.

It is optically coupled by means of an

internal light pipe and mounted in a high

dielectric plastic housing. The LED and

sensor are in hermetically sealed

packages. It is designed for applications

requiring high speed and high voltage

isolation between input and output.
