Hi All,
I have built the attached sensor amplifier which works well.
It outputs to a dvm to give a 0 - 10v reading.
The last two stages U1b and U1c are described as a 2 stage 10hz low pass filter to remove noise from the earlier stages.
What I would like to know is, would this design suffer by any significant margin if I removed the last stage U1c.
I get the feeling the designer may have just used U1c up such , rather than leaving it unused.
My reason for wanting to do so, is that I can then build two amps, with just one quad TL084 chip.
thanks
Richard
