Description

The HCNR200/201 high‑linearity analog optocoupler

consists of a high‑performance AlGaAs LED that illumi‑

nates two closely matched photodiodes. The input pho‑

todiode can be used to monitor, and therefore stabilize,

the light output of the LED. As a result, the non‑linearity

and drift characteristics of the LED can be virtually elimi‑

nated. The output photodiode produces a photocurrent

that is linearly related to the light output of the LED. The

close matching of the photo‑diodes and advanced de‑

sign of the package ensure the high linearity and stable

gain characteristics of the optocoupler.

The HCNR200/201 can be used to isolate analog signals

in a wide variety of applications that require good stabil‑

ity, linearity, bandwidth and low cost. The HCNR200/201

is very exible and, by appropriate design of the appli‑

cation circuit, is capable of operating in many dierent

modes, including: unipolar/bipolar, ac/dc and inverting/

non‑inverting. The HCNR200/201 is an excellent solution

for many analog isolation problems.

Theory of Operation Figure 1 illustrates how the HCNR200/201 high-linearity optocoupler is configured. The basic optocoupler con‑ sists of an LED and two photodiodes. The LED and one of the photodiodes (PD1) is on the input leadframe and the other photodiode (PD2) is on the output leadframe. The package of the optocoupler is constructed so that each photodiode receives approximately the same amount of light from the LED.

Circuit Design Flexibility Circuit design with the HCNR200/201 is very flexible because the LED and both photodiodes are accessible to the designer. This allows the designer to make perf ormance trade-offs that would otherwise be difficult to make with commercially available isolation amplifiers (e.g., bandwidth vs. accuracy vs. cost). Analog isolation circuits can be designed for applications that have either unipolar (e.g., 0-10 V) or bipolar (e.g.
PAGE 18
The preceding circuits were presented to illustrate the flexibility in designing analog isolation circuits using the HCNR200/201. The next section presents several com‑ plete schematics to illustrate practical applications of the HCNR200/201. Example Application Circuits The circuit shown in Figure 16 is a high-speed low-cost circuit designed for use in the feedback path of switchmode power supplies.
PAGE 19
The final circuit shown in Figure 19 isolates a bipolar analog signal using only one optocoupler and generates two output signals: an analog signal proportional to the magnitude of the input signal and a digital signal cor‑ responding to the sign of the input signal. This circuit is especially useful for applications where the output of the circuit is going to be applied to an analog-to-digital converter.
