ISL24005
14-Channel Programmable I2C TFT-LCD Reference Voltage Generator with
Integrated 4-Channel Static Gamma Buffers and Integrated VCOM Calibrator
DATA SHORT
To request the full datasheet, please visit www.intersil.com/products/isl24005
The ISL24005 is a 14-Channel programmable reference
voltage generator with four channels of static gamma buffers
and a programmable V
COM
calibrator.
The ISL24005 is divided into two sets of seven generators: one
is designed to cover the range from V
REFL_L
to V
REFL_H
, and
the other is designed to cover the range from V
REFU_L
to
V
REFU_H
.
The V
COM
calibrator is the sink-current output that attaches
to an external voltage divider. The desired V
COM
setting can
be adjusted by the I
2
C interface.
ISL24005 is available in the 32 Ld Thin QFN package and is
specified for operation over the -40°C to +85°C temperature
range.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
