Product Details

The MAX9888 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX9888 audio codec. The MAX9888 is an integrated audio codec including microphone amplifiers, line amplifiers, an earpiece amplifier, stereo Class D amplifiers, stereo DirectDrive® headphone amplifiers, and digital signal processing. The EV kit also includes Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the device.

The EV kit provides access to all analog and digital inputs/outputs on the device. To enable easy connection to a wide range of audio sources, audio devices are included to convert both USB data and S/PDIF data to I²S.

The EV kit integrates a MAXQ2000 microcontroller to enable I²C communication with devices on the EV kit. The EV kit software, running on a Windows PC, communicates with the EV kit over a standard USB port. The EV kit software provides an intuitive interface to exercise the functions of the device.

The EV kit comes with a MAX9888EWY+ installed.
