Description:
The OPI1268S 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 photologic
device 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.
Applications:
Transportation Systems
PC Board Power Systems
Hybrid Vehicle Systems
Medical Systems
