All versions are No Longer Available.

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 8Ω speakers. The headphone amplifiers operate from a 3VDC to 5.5VDC power supply, and deliver 110mW continuous power into a 16Ω 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.
