TDA8948J
4-channel audio amplifier
[4]
Supply voltage ripple rejection is measured at the output with a source impedance R
SOURCE
= 0
Ω
at the
input and with a frequency range from 20 Hz to 22 kHz (unweighted). The ripple voltage is a sine wave with
a frequency f
ripple
and an amplitude of 300 mV (RMS), which is applied to the positive supply rail.
