Evaluation Kit for the MAX9791A (MAX9791AEVKIT) (MAX9791AEVKIT)

The MAX9791A evaluation kit (EV kit) demonstrates the MAX9791A IC, which combines a stereo Class D power amplifier, a DirectDrive® stereo headphone amplifier, and a 120mA, 4.75V low-dropout regulator (LDO) for notebook, tablet PC, and portable media player applications. Maxim's DirectDrive technology eliminates the need for bulky DC-blocking capacitors at the output of the headphone amplifier.

The EV kit is configured for a 12dB speaker amplifier gain and a 0dB headphone amplifier gain. It is designed to operate from a 4.5V to 5.5V speaker supply and an optional separate 2.7V to 5.5V headphone supply. The EV kit is capable of delivering up to 2W into a pair of 4Ω speakers and 180mW into a 32Ω headphone load.
