Evaluation Kit for the MAX9756 (MAX9756EVKIT) (MAX9756EVKIT)
The MAX9756 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX9756. The MAX9756 is a Class AB amplifier designed to drive stereo bridge-tied-load (BTL) speakers and a stereo headphone in portable audio applications. The speaker amplifiers operate from a 4.5VDC to 5.5VDC power supply, and deliver 2 x 2.3W into a pair of 3Ω speakers. The DirectDrive® headphone amplifiers operate from a 3VDC to 5.5VDC power supply, and deliver 130mW continuous power into a 16Ω stereo headphone.
The MAX9756 features an automatic level control (ALC) on the speaker amplifiers, a 31-step analog volume control, an audible alert input (BEEP), jumper-selectable gain, and a 150mA linear regulator.
The MAX9756 evaluation kit can be used to evaluate the features of the MAX9757 and MAX9758 only. A replacement of the MAX9757/MAX9758 IC is not possible. See the Evaluating the MAX9757/MAX9758 Features section of the full data sheet.
