1. Description

The Broadcom® HCNR201-500E high-linearity analog optocoupler consists of a high-performance AlGaAs LED that illuminates two closely matched photodiodes. The input photodiode monitors, and therefore stabilizes, the light output of the LED. As a result, the nonlinearity 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 close matching of the photodiodes and advanced design of the package ensure the high linearity and stable gain characteristics of the optocoupler. The HCNR201-500E isolates analog signals in a wide variety of applications that require good stability, linearity, bandwidth, and low cost. The HCNR201-500E is flexible and, by appropriate design of the application circuit, is capable of operating in many different modes, including unipolar/ bipolar, AC/DC and inverting/noninverting. The HCNR201-500E is an excellent solution for many analog isolation problems.
