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 dierent
modes, includ ing: unipolar/bipolar, ac/dc and inverting/
non‑inverting. The HCNR200/201 is an excellent solution
for many analog isola tion problems.
