The input of the OPI1268 consists of a high‐efficiency GaAlAs LED with a peak wavelength of 850 nm, which is op cally coupled to the output op cal IC. A photologic device in the output IC detects the incoming modulated light and converts it to a propor onate current. This current is fed into a high‐gain linear amplifier which is temperature, current and voltage compensated. The result is a highly stable digital output with an open collector inverter configura on. This device produces DC and AC voltage isola on between the input and output circuitry while providing TTL signal integrity.
