MAX98089評(píng)估板

The MAX98089 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX98089 audio codec. The IC is an integrated audio codec includ-ing microphone amplifiers, line amplifiers, an earpiece amplifier, stereo Class D amplifiers, stereo DirectDriveM headphone amplifiers, and digital signal processing. The EV kit also includes Windows XPM-, Windows VistaM-, and WindowsM 7-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the IC.

The EV kit provides access to all analog and digital inputs/outputs on the IC. 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, 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 MAX98089EWY+ installed.
