Hallo,
I would like to seek an advice regarding my final project matter. I need to design a surge suppresor circuit which being fed from the output of +and -10V transducer. This Surge Suppresor circuit is used to protect the ADC from any transient or surge current.
I also need to use the opto-coupler circuit to transfer the signal voltage of +and -10V to the input of ADC. Do i need to build the circuit of low-pass filter after the opto-coupler by using the 741 op-amp before the voltage signal is being fed to the input of ADC.
Pppppppppplllllllllzzzzzzzzzzzzzz......help me!

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
