High Voltage Isolator

The OPI1266 is a high voltage Isolator that consists of a GaAIAs LED with a peak wavelength of 890 nm, which is coupled with a unique integrated circuit detector. Photons are collected in the detector by a Photodiode and amplified by a high-gain linear Amplifier that drives a Schottky clamped Open Collector output Transistor The circuit is temperature, current and voltage compensated. Propagation delay times are matched within 500 nanoseconds over the entire temperature range for Timing purposes ( TP = tPHL-tPLH). *UL recognition is for 5833 VAC for one minute. This design produces maximum DC and AC current isolation between the input and output, while providing TTL/LSTTL circuit compatibility. 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 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. By Optek Technology, Inc.
