The HCNR200-500E 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. This can be used to isolate analogue signals in a wide variety of applications that require good stability, linearity and bandwidth. This analogue optocoupler is an excellent solution for many analogue isolation problems.
