1. What max amplitude can i use with my setup? Your integrator uses an inverting topology. So, inverting input is kept at 0V all the time. This means, common mode input voltage range need not to be taken into consideration! As the gain of integrator is 0.28 (see my last post) even a sine with an amplitude of 10V would not make trouble, because output voltage of integrator is only 10V*0.28 = 2.8V. This can easiliy be handled by the TLC2274. Prahlad said:
2. What is the supply voltage to the opamps in your circuit? +-15V. Do use RC-filters (100R + 100µF//100nF) in each supply line. Prahlad said:
3. Can I use TL054 instead of TL084 in your circuit? Of course. Prahlad said:
4. Can I use a TL054 combining the TL051 and TL052 in your circuit? No, I wouldn't do that, because the peak detector produces spike noise, which could be injected into the TL051 section. This would result in an increase of distortion of sine at sine generator output. Prahlad said:
5. What precision is requied with the components is it ok to use 1% Metal Film Resisotrs with your circuit or i need to use better. The Butterworth filters need +-1% caps and the whole circuit needs +-1% metal film resistors. Kai |
