The MAX98050 evaluation system (MAX98050EVSYS#) evaluates the MAX98050, a low-power, high-performance audio CODEC with integrated low-latency digital filters for wireless hearables, headsets, and headphones. The EV system is comprised of two MAX98050 Development Boards (DEV boards), Maxim’s Audio Interface Board III (AUDINT3), Maxim’s Dual EVKit Adapter board, and a USB cable. In addition to the hardware, the MAX98050 Evaluation Software and Hearable Sound Studio Basic software are available for download.

It is recommended that the DEV boards be evaluated with the AUDINT3 board as an EV system. The EV system can be configured as Mono Hardware Setup (1 DEV board) or Stereo Hardware Setup (2 DEV boards). MAX98050 supports standard I²S, left-justified, and TDM digital audio interfaces, as well as I²C for control.

The AUDINT3 board provides all of the necessary supply voltages for proper operation of MAX98050. In addition, the AUDINT3 provides the USB-to-PCM and USB-to-I²C interfaces that are needed to evaluate the system. The Simplified EV System Block Diagrams show details of the DEV boards, Dual EVKit Adapter board and connection with the AUDINT3 board.

For GUIs, there is the MAX98050 Evaluation Software, which provides complete access to all hardware registers. There is also the Hearable Sound Studio Basic software, which facilitates the tuning of the onboard 5 band playback equalizer, digital filter channels, and the digital filter dynamic range compression (DRC).
