OPI1268 vs OPI1268S vs OPI1268 Comparison

The OPI1268 is a 1-channel 5-pin High Voltage Isolator with a digital output that is capable of high speed data transmission. The input of the OPI1268 consists of a high‐efficiency GaAlAs LED with a peak wavelength of 850nm, 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 which 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. It is suitable for data transmission for high voltage isolation, PC board power system isolation and office equipment.
