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.
