The MAX9750A evaluation kit (EV kit) is a fully assembled
and tested circuit board that evaluates the
MAX9750A/B/C, MAX9751, and MAX9755. The
MAX9750A/B/C, MAX9751, and MAX9755 are class AB
amplifiers 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 1.4W
continuous power into a pair of 8 speakers. The headphone
amplifiers operate from a 3VDC to 5.5VDC power
supply, and deliver 110mW continuous power into a 16 stereo headphone.
The MAX9750A/B/C feature an analog volume control and
an audible alert input (BEEP). The MAX9750A/B/Cs' gain
is jumper selectable. The MAX9751 features a 2:1 multiplexer,
allowing two audio sources. The MAX9750A/B/C/MAX9751/MAX9755 have a low shutdown supply current
of 5µA.
