Description
The MAX9738 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.
The MAX9738 is ideally suited to deliver the high output voltage swing required to drive ceramic/piezoelectric speakers.
The device utilizes fully differential inputs and outputs, comprehensive click-and-pop suppression, shutdown control, and soft-start circuitry. The MAX9738 is fully specified over the -40°C to +85°C extended temperature range and is available in an ultra-small, lead-free 5x4 WLP (2.5mm x 2mm) package.
