2.4W, Single-Supply, Class G Power Amplifier  
MAX9730  
General Description  
Features  
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  
8Ω load. The 2.4W output power allows for transient  
audio content to remain unclipped as the battery rail col-  
lapses over time.  
o 2.7V to 5.5V Operation  
o Integrated Charge-Pump Power Supply  
o 63% Efficiency (V = 5V, P = 1W)

o Small Thermally Efficient Packages  
2mm x 2.5mm 20-Bump WLP  
4mm x 4mm 28-Pin TQFN  
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.  
Ordering Information  
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.
