(1) Inphase and negative phase NF capacitor charging time
In (Fig.2), when the power source is turned on, Q1 and Q2 are turned on, and NF capacitors are charged in
the route of VCC→Q2→R→boot→CBS→out→R0→CNF. For instance, if the capacity of an inphase capacitor
is not properly paired with that a negativephase capacitor, output offset voltage = pop noise is produced
because a charging time of NF capacitor differs between the inphase and negativephase outputs.
Therefore, to suppress the pop noise it is necessary to properly pair the inphase and negativephase NF
capacitors. Output and NF DC voltage waveforms by the pairing of NF capacitors: CNF are shown in (Fig.3)
and (Fig.4).
Further, voltage waveforms are shown when the power source was turned on, under the following conditions:
VCC = 13.2V, RL = 4, Ta = 25°C, and input shotcircuit.
Output DC voltage VOUT: (2V / div, 200ms / div)
NF DC voltage VNF: (1V / div, 200ms / div)
