Optocoupler DC-IN 1-CH Linear Photovoltaic DC-OUT 8-Pin PDIP W SMD T/R
Manufacturer Part #: HCNR200-500E
Avnet Manufacturer Part #: HCNR200-500E
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.
