Product Details

The MAX5X02 evaluation kit (EV kit) demonstrates the MAX5702 and MAX5802 12-bit, 2-channel, low-power DACs with internal reference and buffered voltage outputs. The EV kit provides controls to change the DAC outputs, power operations, and references.
The DAC ICs are controlled by an on-board MAXQ® microcontroller that provides two different selectable interface options: I²C and SPI. The EV kit features Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple graphical-user interface (GUI) for exercising the features of the ICs.
The EV kit comes with the MAX5702AAUB+ (SPI) and the MAX5802AAUB+ (I²C) installed. Contact the factory for samples of the pin-compatible MAX5700AUB+ (SPI, 8-bit), MAX5701AUB+ (SPI, 10-bit), MAX5702BAUB+ (SPI, 12-bit), MAX5800AUB+ (I²C, 8-bit), MAX5801AUB+ (I²C, 10-bit), MAX5802BAUB+ (I²C, 12-bit) versions.
