MAX9730 2.4W, Single-Supply Class G Power Amplifier

The MAX9730 features a mono Class G power Amplifier wit 657 h 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 high-performance 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 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 -40C to +85C extended temperature range and is available in ultra-small, lead-free, 20-bump WLP (2mm x 2.5mm) and 28-pin TQFN (4mm x 4mm) packages.
