HCPL-4562 Description
The HCPL-4562 and HCNW4562 optocouplers provide wide-bandwidth isolation for analog signals. They are ideal for video isolation when bined with their application circuit (Figure 4). High linearity and low phase shift are achieved through an AlGaAs LED bined with a high-speed detector.
