The Maxim Integrated evaluation kit (EV kit) for MAX98090 (TQFN) is a fully assembled and tested circuit board that evaluates the MAX98090 (TQFN) audio codec. The MAX98090 is an integrated audio codec including an earpiece amplifier, stereo Class D amplifier, stereo Direct Drive headphone amplifier, and digital signal processing. To enable easy connection to a wide range of audio sources, the EV kit includes audio devices to convert both USB and S/PDIF data to I2S data. The EV kit also integrates a MAXQ2000 microcontroller to enable I2C and SPI communication with the on-board I2C- and SPI-capable devices. A simple and intuitive graphical user interface (GUI) provides communication with the EV kit through Windows OS running Windows XP -, Windows 7-, or Windows 8-compatible software.
