(1) In-phase 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 in-phase capacitor
is not properly paired with that a negative-phase capacitor, output offset voltage = pop noise is produced
because a charging time of NF capacitor differs between the in-phase and negative-phase outputs.
Therefore, to suppress the pop noise it is necessary to properly pair the in-phase and negative-phase 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 shot-circuit.
Output DC voltage VOUT: (2V / div, 200ms / div)
NF DC voltage VNF: (1V / div, 200ms / div)
