2.2 W BTL audio amplifier
14.2 BTL dynamic characterization
The total harmonic distortion-plus-noise (THD+N) as a function of frequency (
Figure 7
)
was measured with a low-pass filter of 80 kHz. The value of capacitor C2 influences the
behavior of PSRR at low frequencies; increasing the value of C2 increases the
performance of PSRR.
