Programmable 18-Channel Gamma with
1-Channel V_COM with Reference
The EL5625 represents a high integration programmable
buffer solution from Intersil. The device integrates 18-
channels of programmable buffers, with a single
programmable V_COM, a reference output, and a supply side
LDO.
The 18-channel programmable buffers have 11-bit resolution
and rail-to-rail outputs. Each output is capable of driving
15mA continuous.
The V_COM output also features 11-bits of resolution. The
generated voltage is connected to the non-inverting input of
the integrated V_COM amplifier. This amplifier has a short-
circuit current of 1A, 100mA continuous.
The integrated low drop-out regulator is used, in conjunction
with an external transistor, to provide a solid supply voltage
to the device. It features 200mV minimum drop-out and has
very good load regulation for the cleanest gamma and V_COM
outputs.
The EL5625 also includes over-temperature protection and
is available in a 38-pin QFN package.

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.
