The MAX9877 evaluation kit (EV kit) is an assembled and tested printed-circuit board (PCB) that evaluates the MAX9877 IC. The MAX9877 is a Class D audio power amplifier and stereo DirectDrive™ headphone amplifier communicating over a 2-wire I²C interface. The MAX9877 features user-defined input configuration, input gain, input source, output enable, volume control, and oscillator frequency-modulation modes. The user-defined features are programmed through the I²C-compatible serial interface, communicating at data rates up to 400kbps. The I²C data is sent through an on-board USB interface circuit using a computer or a user-supplied I²C bus.
The EV kit also features Windows 2000/XP/Vista®-compatible software that provides a user interface for exercising the MAX9877's features. The program is menu driven and offers a graphical user interface (GUI) complete with buttons, checkboxes, and track bars.
