Description

The HCNR200/201 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 HCNR200/201 can be used to isolate analog signals

in a wide variety of applications that require good stabil-

ity, linearity, bandwidth and low cost. The HCNR200/201

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 HCNR200/201 is an excellent solution

for many analog isolation problems.
