= 50 pF (valid for master mode only).
Device measured with external components shown in recommended application diagram Fig.8.
Input is 1 kHz and
60 dB.
Input is 1 kHz and 0 dB.
Measured by applying a 1 kHz, 0 dB signal to one channel and monitoring the level of 1 kHz (fundamental) on the
other channel.
See also Section “Input level” of Chapter “Functional description”; valid for left or right channel.
