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 confgurations.
