HCNR200-500E

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 photocur rent

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 opto coupler.
