CARROLLTON, Texas, Feb. 25, 2010 – TT electronics Optek Technology’s OPI1268 optical isolator delivers AC and DC voltage isolation up to 16 kV while achieving digital data transmission rates of 2 MBd. It is UL-recognized and designed for power isolation in high-voltage PC board circuits in industrial electronics systems, medical electronic equipment and office machines.
The output integrated circuit (IC) detects the incoming optical signal and converts it to a proportionate current, which is fed through a linear amplifier and compensated for temperature, current and voltage, resulting in stable digital output with an open collector inverter configuration.
The device comprises a GaAlAs LED with a peak wavelength of 850 nm, optically coupled to a Photologic photodiode in the output IC. Packaged in an opaque plastic housing, it measures 27.94 × 6.35 × 8.89 mm and operates from -40 to 100 °C.
