2.4W, Single-Supply, Class G Power Amplifier
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 output current over a 2.7VDC to 5.5VDC supply voltage range, guaranteeing up to 2.4W output power into an 8 load. The 2.4W output power allows for transient audio content to remain unclipped as the battery rail collapses over time. The MAX9730 maximizes battery life by offering highperformance efficiency. Maxim's proprietary output stage provides efficiency levels greater than Class AB devices without the EMI penalties commonly associated with Class D amplifiers. High efficiency allows the MAX9730 to be packaged in a UCSPTM 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 cir
