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!

Hi Faz,

How about a pair of zener diodes?
