General Description
The MAX9730 features a mono Class G power amplifier
with an integrated inverting charge-pump power supply.
The charge pump can supply up to 500mA of peak out-
put current over a 2.7VDC to 5.5VDC supply voltage
range, guaranteeing up to 2.4W output power into an
8
Ω load. The 2.4W output power allows for transient
audio content to remain unclipped as the battery rail col-
lapses over time.
The MAX9730 maximizes battery life by offering high-
performance efficiency. Maxim’s proprietary output
stage provides efficiency levels greater than Class AB
devices without the EMI penalties commonly associat-
ed with Class D amplifiers. High efficiency allows the
MAX9730 to be packaged in a WLP package without
derating the output power handling capability.
The device utilizes fully differential inputs and outputs,
comprehensive click-and-pop suppression, shutdown
control, and soft-start circuitry. The MAX9730 is fully
specified over the -40°C to +85°C extended tempera-
ture range and is available in ultra-small, lead-free,
20-bump WLP (2mm x 2.5mm) and 28-pin TQFN (4mm
x 4mm) packages.
