Product Details

The MAX5825A evaluation kit (EV kit) demonstrates the MAX5825A 12-bit, 8-channel, low-power DAC with selectable internal references and buffered voltage output. The IC comes in a 20-pin TSSOP package. The EV kit provides control to change the DAC's outputs, power operations, references, and watchdog timer settings.
The IC features a watchdog function that can be enabled to monitor the I/O interface for activity and integrity.
The EV kit includes a USB-to-I²C 400kHz interface circuit. The EV kit features Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple graphical user interface (GUI) for exercising the IC's features.
The EV kit comes with the MAX5825AAUP+ installed, which is the 12-bit I²C version. Contact the factory for samples of the pin-compatible MAX5823AUP+ (8-bit), MAX5824AUP+ (10-bit), and MAX5825BAUP+ (12-bit) versions.
