DATASHEET
EL5224, EL5324, EL5424
12MHz Rail-to-Rail Buffers + 100mA V
COM
Amplifier
The
EL5224, EL5324,
and
EL5424
feature 8, 10, and 12 low
power buffers, respectively, and one high power output
amplifier. They are designed primarily for buffering column
driver reference voltages in TFT-LCD applications as well as
generation of the V
COM
supply. Each low power buffer features
a -3dB bandwidth of 12MHz and features rail-to-rail
input/output capability. The high power buffer can drive
100mA and swings to within 2V of each rail.
The 8-channel EL5224 is available in 24 Ld QFN and 24 Ld
HTSSOP packages, the 10-channel EL5324 is available in
32 Ld QFN and 28 Ld HTSSOP packages, and the 12-channel
EL5424 is available in the 32 Ld QFN package. They are
specified for operation across the full -40°C to +85°C
temperature range.

NOTES:
1. Intersil Pb-free 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.
2. For Moisture Sensitivity Level (MSL), see product information pages for
EL5224, EL5324, EL5424.
For more information on MSL, refer to
TB363.
