how about if I want to give a bipolar input which is +-10V dc to the optocoupler? I came across on the product of H11AA1. Does it really suitable for my application to fed the optocoupler to the ADC part which the voltage signal is +-10V also.

Do i need a low pass filter or a buffer circuit by using the op-amp of 741 after the optocoupler to fed the ADC input.

PLLLLZZZzzzzzzzzz....give an idea ;D
