Optoisolator Delivers Up To 16kV Isolation At 2Mbd
The output IC detects the incoming optical signal and converts it to a proportionate current, which is fed through a high-gain linear amplifier and compensated for temperature, current and voltage, resulting in a stable digital output with an open collector inverter configuration. The OPI1268 optoisolator combines a high-efficiency gallium aluminium arsenide (GaAlAs) light-emitting diode (LED) with a peak wavelength of 850nm, optically coupled to a Photologic photodiode in the output IC.
Forward current (IF) is 10mA typical/50mA maximum, with typical propagation delays (tPHL-tPLH) less than or equal to 500ns. The creepage distance/air path is 0.970in (24.64mm) and the devices are UL recognised under file E58730. Packaged in an opaque high-dielectric plastic housing, the OPI1268 device measures 27.94 x 6.35 x 8.89mm and has a five-lead configuration (cathode, anode, Vcc, output and ground). The operating temperature range is from -40C to +100C. Data and samples are available now from Pacer.
