9.2.1 Audio Frequency Performance
The OPA836 and OPA2836 devices provide excellent audio performance with low quiescent power. To show performance in the audio band, an audio analyzer from Audio Precision (2700 series) tests THD+N and FFT at 1 VRMS output voltage.
Figure 9-11 shows the circuit used for the audio-frequency performance test.
The 100-pF capacitor to ground on the input helped to decouple noise pick up in the lab and improved noise performance.
