Product Details

The MAX9694 evaluation kit (EV kit) demonstrates the MAX9694 reference voltage generator for gamma correction in TFT-LCD panels, such as those found in high-resolution TVs, high-end monitors, or for general industrial reference voltage generation. The MAX9694 EV kit provides 14 programmable reference voltage outputs (DAC outputs), four static buffered reference voltage outputs (reference outputs), and a 7-bit digital variable reference (DVR) for VCOM voltage calibration. The EV kit can use a 9V to 20V DC power supply for powering the application circuit.

The EV kit features a USB-to-I²C interface circuit. Windows® 2000/XP- and Windows Vista®-compatible software, with a graphical user interface (GUI), is available for exercising the MAX9694 features. The EV kit can also connect to a user-supplied I²C interface circuit for stand-alone MAX9694 operation.
