High Voltage Isolator OPI1268 Features:
TTL compa ble output 16 KV isola on 2Mbit/s tPHL‐tPLH ≤ 500 ns Creepage path: 0.970” (24.64 mm) Air path: 0.970” (24.64 mm) UL recognized file No. E58730*
Descrip on: The OPI1268 is a 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 850 nm, which is op cally coupled to the output op cal IC. A photodiode 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.
