HCPL-4562, HCNW4562
High Bandwidth, Analog/Video Optocouplers
Data Sheet
Description
Features
• Wide bandwidth[1]:
17 MHz (HCPL-4562)
9 MHz (HCNW4562)
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 (Figure4). 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.
• 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

*The Input-Output MomentaryWithstandVoltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage
rating. For the continuous voltage rating refer to the VDE 0884 Insulation Related Characteristics Table (if applicable), your equipment level safety
specification or Avago Application Note 1074 entitled “Optocoupler Input-Output Endurance Voltage,”publication number 5963-2203E.

Conversion from HCPL-4562 to HCNW4562
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.
Figure 15 shows the dependency of the DC output
voltage on hFEX
.
For 9 V < VCC < 12 V, select the value of R11 such that

Design Considerations of the Application Circuit
The voltage gain of the second stage (Q3) is
approximately equal to:
The appÏication 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′11 (R′11 includes the parallel combination of
R11 and the load impedance) or reducing R9 (keeping
R9/R10 ratio constant) will improve the bandwidth.
To use the circuit, first select R1 to set VE for the desired
LED quiescent current by:
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.

For a constant value VINp-p, the circuit topology
(adjusting the gain with R4) preserves linearity by
keeping the modulation factor (MF) dependent only

Finally, adjust R4 to achieve the desired voltage gain.
