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 photocur rent

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 opto coupler.

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 appro priate design of the appli‑

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

modes, includ ing: unipolar/bipolar, ac/dc and inverting/

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

for many analog isola tion problems.
