HCNR200/201
High-Linearity Analog Optocouplers
Data Sheet
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
non-linearity and drift characteristics of the LED can
be virtually eliminated. 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 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.
