Product Description

The HCNR200/201 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 HCNR200/201 can be used to isolate analog signals in a wide variety of applications that require good stabil‑ ity, linearity, bandwidth and low cost. The HCNR200/201 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 HCNR200/201 is an excellent solution for many analog isolation problems.
