Description
The HCNR200/201 high-linearity
analog optocoupler consists of a
high-performance AlGaAs LED
that illuminates two closely
matched photodiodes. The input
photodiode can be used to
monitor, and therefore stabilize,
the light output of the LED. As a
result, the nonlinearity and drift

characteristics of the LED can be
virtually eliminated. The output
photodiode produces a photocur-
rent that is linearly related to the
light output of the LED. The close
matching of the photodiodes and
advanced design 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 stability, linearity,
bandwidth and low cost. The
HCNR200/201 is very flexible
and, by appropriate design of the
application 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.
