2. TYPICAL CONNECTION DIAGRAM
Notes:
1. Recommended values for the default charge pump switching
frequency. The required capacitance follows an inverse
relationship with the charge pump’s switching frequency. When
increasing the switching frequency, the capacitance may
decrease; when lowering the switching frequency, the
capacitance must increase.
2. Larger capacitance reduces the ripple on the internal
amplifier’s supply. This may reduce the distortion at higher
output power levels.
3. Additional bulk capacitance may be added to improve PSRR
at low frequencies.
4. Series resistance in the path of the power supplies must be
avoided. Any voltage drop on VHP will directly impact the
negative charge pump supply (-VHPFILT) and clip the audio
output.
