Multi-Channel Buffers Plus VCOM Driver
The ISL24003 integrates eighteen gamma buffers and a
single VCOM buffer for use in large panel LCD displays of
10” and greater. Half of the gamma channels in each device
are designed to swing to the upper supply rail, with the other
half designed to swing to the lower rail. The output capability
of each channel is 10mA continuous, with 120mA peak. The
gamma buffers feature a 10MHz 3dB bandwidth
specification and a 9V/µs slew rate.
The VCOM amplifier is designed to swing from rail to rail. The
output current capability of the VCOM in the ISL24003 is
60mA continuous, 150mA peak, and a slew rate of 50V/µs.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are 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.
