High-Voltage Isolator

The OPI1268 is a high-voltage isolator with a digital output that is capable of high-speed data transmission. The input of theOPI1268 consists of a high-efficiency GaAlAs LED with a peak wavelength of 850 nm, which is optically coupled to the output optical IC. A photodiode in the output IC detects the incoming modulated light and converts it to a proportionate current.
This current is fed into a high-gain linear amplifier that is temperature, current, and voltage compensated. The result is a highly stable digital output with an open collector inverter configuration. This device produces DC and AC voltage isolation between the input and output circuitry while providing TTL signal integrity.

Features

  • TTL compatible output
