Product Details

The Maxim command module (MINIQUSB) receives commands from a PC through the USB to create an SPI™ or SMBus™/I²C-compatible interface. Maxim evaluation kits (EV kits) that make use of the MINIQUSB require custom software, and can be ordered together as an evaluation system (EV system). Ordering information for EV systems is located in the EV kit data sheet.

An EV system is an EV kit combined with an interface board such as a MINIQUSB and custom software. Refer to the appropriate EV kit manual for quick start and detailed operating instructions.

The MINIQUSB module is provided as part of selected Maxim EV systems for the purpose of evaluating Maxim/Dallas parts only. The use of the MINIQUSB as a development target is not supported. Refer to the MAXQ2000 Evaluation Kit data sheet for this purpose.

For Windows® 95 or Windows NT support, the CMOD232 or CMAXQ232* should be used instead.

Product Details

When used as a component in the MAX98357/MAX98358 dev kit or evsys NO driver is required.

The Maxim Audio Interface 1 (AUDINT1) board provides both an I2C and I2S interface to facilitate the evaluation of compatible Maxim Development (DEV) boards. Maxim DEV boards that are evaluated with the AUDINT1 interface board can require custom GUI software, which is available as a download from Maxim’s evkit-software web page.

The AUDINT1 board and a compatible DEV board are ordered together as an evaluation system (EV system). Ordering information for EV systems is located in the EV system data sheet.

Refer to the appropriate EV system data sheet for quick start and detailed operating instructions.

The AUDINT1 board is provided as part of selected Maxim evaluation systems (EV system) to evaluate Maxim parts only. The use of the AUDINT1 board as a development target is not supported. Refer to the MAXQ2000 evaluation kit data sheet for this purpose.
