Beginning to build a sine wave generator for 1KHz sine to test amplifier circuits for distortion. I have several examples I will be working from. The idea is to have ultra low distortion in the 0.005 or better range. My question is in the low pass filter of the Op Amp circuit what is the best capacitor type , Ceramic, mica, Polyester film? Yes I know the choice of Op Amp is critical for low distortion, I have several Burr Brown op amps that will more than meet the spec, so really the question is strictly about the capacitor.
