14-Channel Programmable I2C TFT-LCD
Reference Voltage Generator with
Integrated 4-Channel Static Gamma
Buffers and Integrated VCOM Calibrator
The ISL24005 is a 14-Channel programmable reference
voltage generator with four channels of static gamma buffers
and a programmable VCOM calibrator.
The ISL24005 is divided into two sets of seven generators: one
is designed to cover the range from VREFL_L to VREFL_H, and
the other is designed to cover the range from VREFU_L to
VREFU_H.
The VCOM calibrator is the sink-current output that attaches
to an external voltage divider. The desired VCOM setting can
be adjusted by the I2C 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.
