High Bandwidth, Analog/Video Optocouplers
Data Sheet
Description
The HCPL-4562 and HCNW4562 optocouplers provide
wide bandwidth isolation for analog signals. They are ideal
for video isolation when combined with their application
circuit (Figure 4). High linearity and low phase shift are
achieved through an AlGaAs LED combined with a high
speed detector. These single channel optocouplers are
available in 8-Pin DIP and Widebody package
congurations.
