Faz Posted November 5, 2006 Report Share Posted November 5, 2006 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!
