HCNR200 and HCNR201

High-Linearity Analog Optocouplers

Description

The HCNR200/201 high-linearity analog 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 photocur rent that is linearly related to the light output of the LED. The close matching of the photo-diodes and advanced design of the package ensure the high linearity and stable gain characteristics of the opto coupler.

The HCNR200/201 can be used to isolate analog signals in a wide variety of applications that require good stability, linearity, bandwidth and low cost. The HCNR200/201 is very fl exible and, by appro priate design of the application circuit, is capable of operating in many diff erent modes, includ ing: unipolar/bipolar, ac/dc and inverting/ non-inverting. The HCNR200/201 is an excellent solution for many analog isola tion problems.
