For this example, the OPA1611, a high-performance audio operational amplifier (op amp), was chosen as a low noise and low distortion foundation for the circuit. Thin film precision resistors in 1206 packages are used for all resistances in order to minimize distortion contributions aside from those arising from the capacitors.

In earlier tests ('Dynamic testing of audio amplifiers', Hi-Fi News, Nov.1970, p1655), the distortion of the 303 including output capacitor was extracted while using a music test signal, and the distortion alone without the masking effect of the music was found to be inaudible, and had to be increased many times before becoming audible.

Selecting capacitors to minimize distortion in audio ...

Selecting capacitors to minimize distortion in audio applications Introduction The use of capacitors in an audio signal chain is often fraught with mysticism and little quantitative analysis to justify capacitor selection. With many capacitors costing more than the integrated circuits they serve, it is a chal-

Signal distortion from high-K ceramic capacitors John Caldwell, Analog Applications Engineer, Texas Instruments - June 16, 2013 Introduction Multilayer ceramic capacitors (MLCCs) are used extensively in modern electronics because they offer high volumetric efficiencies and low equivalent series resistances at attractive prices. These

Ceramic vs. Polystyrene Capacitor Distortion Analysis ...

The second is four ceramic disc caps in place of the poly caps. No other changes. I performed this test yesterday at 1KHz and found small differences that only my Tektronix AA501 Distortion Analyzer could detect reliably, but today I used 100Hz as the test frequency and the differences amplified 100-fold.
