HCNW4562
HighBandwidth,Analog/VideoOptocouplers
DataSheet
Description
Features
The HCPL-4562 and HCNW4562 optocouplers provide • Wide bandwidth[1]:
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 configurations.
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
Functional Diagram
• Safety approval:

Conversion from HCPL-4562 to HCNW4562
For 9 V < VCC < 12 V, select the value of R11 such
that
In order to obtain similar circuit performance when
converting from the HCPL-4562 to the HCNW4562,
it is recommended to increase the Quiescent Input
Current, IFQ, from 6 mA to 10 mA. If the application
circuit in Figure 4 is used, then potentiometer R4
should be adjusted appropriately.

The application circuit in Figure 4 incorporates
several features that help maximize the bandwidth
performance of the HCPL-4562/HCNW4562. Most
important of these features is peaked response of
the detector circuit that helps extend the frequency
range over which the voltage gain is relatively
constant. The number of gain stages, the overall
circuit topology, and the choice of DC bias points
are all consequences of the desire to maximize
bandwidth performance.

Increasing R′ (R′ includes the parallel

combination of R11 and the load impedance) or
reducing R9 (keeping R9/R10 ratio constant) will
improve the bandwidth.
If it is necessary to drive a low impedance load,
bandwidth may also be preserved by adding an
additional emitter following the buffer stage (Q5 in
Figure 16), in which case R11 can be increased to
set ICQ4 2 mA.
