Product Details

The MAX5X05 evaluation kit (EV kit) demonstrates the MAX5705 and MAX5805 12-bit, single-channel, low-power DACs with internal reference and buffered voltage output. The MAX5705 and the MAX5805 come in a 10-pin µMAX® package. The EV kit provides controls to change the DAC output, power operations, and references. The DAC ICs are controlled by an on-board MAXQ microcontroller, which provides two different interfaces: I²C and SPI. The EV kit features Windows XP®-, Windows Vista®-, and Windows® 7-compatible software, which provides a simple graphical user interface (GUI) for exercising the MAX5705 and the MAX5805 features.

The EV kit comes with the MAX5705AAUB+ (SPI) and the MAX5805AAUB+ (I²C) installed. Contact the factory for samples of the pin-compatible MAX5703AUB+ (SPI, 8-bit), MAX5704AUB+ (SPI, 10-bit), MAX5705BAUB+ (SPI, 10-bit), MAX5803AUB+ (I²C, 8-bit), MAX5804AUB+ (I²C, 10-bit), MAX5805BAUB+ (I²C, 12-bit).
