MAX9660 Evaluation Kit
General Description
The MAX9660 evaluation kit (EV kit) demonstrates the
MAX9660 programmable VCOM voltage buffer used for
VCOM backplane voltage calibration in TFT-LCD pan-
els, such as those found in high-resolution TVs, and
high-end monitors. A 7-bit digital-to-analog converter
(DAC) sinks current from an external resistor-divider to
set a VCOM reference voltage. An external resistor sets
the full-scale range of sinking current. The IC can drive
±100mA continuous current and up to ±900mA peak
current. The desired DAC value can be stored in non-
volatile multiple one-time programmable (MOTP) mem-
ory and is recalled at each power-up. The EV kit oper-
ates from an 8V to 20V DC power supply.
The MAX9660 EV kit features a USB-to-I 2 C interface cir-
cuit. Windows ? 2000/XP ? - and Windows Vista ? -com-
patible software, with a graphical user interface (GUI),
available for exercising the MAX9660 features. The EV
kit can also connect to a user-supplied I 2 C interface
