Hi i am developing a circuit with some opamps stages like inverting amplifier, non-inverting amplifier, precision rectifier, first and second order active filters and finally the signal goes to an PIC's ADC. Should i place buffers between stages or it is not necessary? The circuit is attached. Some of the words are in portguese but i think the stages are self explaned. Can i remove any of the buffers?
Thanks
Thanks
