HCNR200

The HCNR200 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 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 is very flexible and, by appropriate 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 is an excellent solution for many analog isolation problems.
