HCPL-4562 Overview
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.
HCPL-4562 Key Features
- Wide bandwidth[1]
- 17 MHz (HCPL-4562)
- 9 MHz (HCNW4562)
- High voltage gain[1]
- 2.0 (HCPL-4562)
- 3.0 (HCNW4562)
- Low GV temperature coefficient: -0.3 %/°C
- Highly linear at low drive currents
- High-speed AlGaAs emitter
- Safety approval
HCPL-4562 Applications
- Video isolation for the following standards/formats: NTSC, PAL, SECAM, S-VHS, ANALOG RGB
- Low drive current feedback element in switching power supplies (for ISDN networks, as an example)
