The HCNR201 high-linearity analog optocouplerconsists 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-linearityand drift characteristics of the LED can be virtually elimi‑nated. The output photodiode produces a photocurrentthat is linearly related to the light output of the LED. Theclose matching of the photo-diodes and advanced de‑sign of the package ensure the high linearity and stablegain characteristics of the optocoupler.The HCNR200/201 can be used to isolate analog signalsin a wide variety of applications that require good stabil‑ity, linearity, bandwidth and low cost. The HCNR200/201is very flexible and, by appropriate design of the appli‑cation circuit, is capable of operating in many differentmodes, including: unipolar/bipolar, ac/dc and inverting/non-inverting. The HCNR200/201 is an excellent solutionfor many analog isolation problems.
