The MAX98088 evaluation kit (EV kit) is a fully assembled
and tested circuit board that evaluates the MAX98088
audio codec. The MAX98088 IC is an integrated audio
codec including microphone amplifiers, line amplifiers,
an earpiece amplifier, stereo Class D amplifiers, stereo
DirectDrive
processing. The EV kit also includes Windows XP
Windows Vista
that provides a simple graphical user interface (GUI) for
exercising the features of the IC.
The EV kit provides access to all analog and digi-
tal inputs/outputs on the IC. To enable easy con-
nection to a wide range of audio sources, audio
devices are included to convert both USB data and
S/PDIF data to I
The EV kit integrates a MAXQ2000 microcontroller to
enable I
The EV kit software, running on a Windows PC, commu-
nicates with the EV kit over a standard USB port. The EV
kit software provides an intuitive interface to exercise the
functions of the IC.
The EV kit comes with a MAX98088EWY+ installed.
