HCNR201-500E

The HCNR201-500E is a High-linearity Analogue 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 photocurrent that is linearly related to the light output of the LED. The optocoupler can be used to isolate analogue signals in a wide variety of applications that require good stability, linearity and bandwidth. By appropriate design of the application circuit is capable of operating in many different modes. This is an excellent solution for many analogue isolation problems.
