The MAX9590 evaluation kit (EV kit) is a fully assembled
and tested circuit board that evaluates the MAX9590.
The MAX9590 EV kit provides 14 programmable voltage
references and 4 static voltage references for
gamma correction in TFT-LCD displays. Two register
banks are provided to store two sets of gamma reference
values. Gamma values are programmed into the
banks through the I²C interface, and the settling time
for outputs is less than 0.5µs.
The 14 programmable reference voltages are divided
evenly into seven upper and seven lower voltages for
the upper and lower gamma curves of LCD column drivers.
The 14 programmable buffers wake-up in a high-impedance
state until the registers are programmed.
This protects the LCD system from high transient currents
during the startup phase.
The EV kit includes Windows® 98SE/2000/XP-compatible
software that provides a graphical user interface
(GUI) for exercising the features of the MAX9590.
The MAX9590 evaluation system (EV system) consists
of the MAX9590EVKIT and a companion CMAXQUSB
serial interface board. The CMAXQUSB interface board
allows a PC to control an I²C interface using its USB
port. Order the MAX9590EVCMAXQU for a complete
PC-based evaluation of the MAX9590. Order the
MAX9590EVKIT if you already have a MAX9590 compatible
serial interface.
