MAX9756 Evaluation Kit
General Description
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
Features
o 4.5VDC to 5.5VDC Single-Supply Operation
o Drives 2 x 2.3W into a Pair of 3 ? Speakers
o Drives 130mW into a 16 ? Stereo Headphone
o Automatic Level Control on Speaker Amplifiers
amplifiers operate from a 4.5VDC to 5.5VDC power sup-
ply, and deliver 2 x 2.3W into a pair of 3 ? speakers. The
DirectDrive ? headphone amplifiers operate from a
3VDC to 5.5VDC power supply, and deliver 130mW
continuous power into a 16 ? stereo headphone.
The MAX9756 features an automatic level control (ALC)
on the speaker amplifiers, a 31-step analog volume
