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 flexible and, by approp riate design of the appli‑
cation circuit, is capable of operating in many different
modes, including: unipolar/bipolar, ac/dc and inverting/
non-inverting. The HCNR200/201 is an excellent solution
for many analog isolation problems.
