High Bandwidth, Analog/Video Optocouplers
Data Sheet
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
congurations.

Notes:
1. When used in the circuit of Figure 1 or Figure 4; GV = VOUT/VIN; IFQ = 6 mA (HCPL-4562), IFQ = 10 mA (HCNW4562).
2. Derate linearly above 70°C free-air temperature at a rate of 2.0 mW/°C (HCPL-4562).
3. Maximum variation from the best t line of IPB vs. IF expressed as a percentage of the peak-to-peak full scale output.
4. CURRENT TRANSFER RATIO (CTR) is dened as the ratio of output collector current, IO, to the forward LED input current, IF, times 100%.
5. Device considered a two-terminal device: Pins 1, 2, 3, and 4 shorted together and Pins 5, 6, 7, and 8 shorted together.
6. Flat-band, small-signal voltage gain.
7. The frequency at which the gain is 3 dB below the at-band gain.
8. Dierential gain is the change in the small-signal gain of the optocoupler at 3.58 MHz as the bias level is varied over a given range.
9. Dierential phase is the change in the small-signal phase response of the optocoupler at 3.58 MHz as the bias level is varied over a given
range.
10. TOTAL HARMONIC DISTORTION (THD) is dened as the square root of the sum of the square of each harmonic distortion component. The THD
of the isolated video circuit is measured using a 2.6 kΩ load in series with the 50 Ω input impedance of the spectrum analyzer.
11. ISOLATION MODE REJECTION RATIO (IMRR), a measure of the optocoupler’s ability to reject signals or noise that may exist between input and
output terminals, is dened by 20 log10 [(VOUT/VIN)/(VOUT/VIM)], where VIM is the isolation mode voltage signal.
12. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥4500 V rms for 1 second (leakage detec-
tion current limit, II-O ≤5 µA). This test is performed before the 100% Production test shown in the IEC/EN/DIN EN 60747-5-2 Insulation Related
Characteristics Table, if applicable.
13. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥6000 V rms for 1 second (leakage detec-
tion current limit, II-O ≤5 µA). This test is performed before the 100% Production test shown in the IEC/EN/DIN EN 60747-5-2 Insulation Related

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.
Design Considerations of the Application Circuit
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.
To use the circuit, rst select R1 to set VE for the desired
LED quiescent current by:
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

For a constant value VINp-p, the circuit topology
(adjusting the gain with R4) preserves linearity by
keeping the modulation factor (MF) dependent only
on VE.
Modulation
For a given GV, VE, and VCC, DC output voltage will vary
only with hFEX.
Where:
and,
The voltage gain of the second stage (Q3) is
approximately equal to:
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.
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.
Finally, adjust R4 to achieve the desired voltage gain.
