EL5524, EL5624, EL5724, EL5824
Integrated Buffers with V
COM
The EL5524, EL5624, EL5724, and EL5824 integrate a
number of gamma reference buffers with a single V
COM
amplifier. The EL5524 contains 4 gamma buffers, the
EL5624 contains 6, the EL5724 contains 8, and the EL5824
contains 10. Each gamma buffer has a bandwidth of 12MHz
and features a slew rate of 15V/s. The output current is
rated at 30mA continuous, 140mA peak.
The V
COM
amplifiers are rated for 60mA continuous output
current and 200mA peak. They also feature higher slew rate
and bandwidth for use in error cancellation circuits.
The EL5524 is available in the 14-pin HTSSOP package, the
EL5624 in the 20-pin HTSSOP package, the EL5724 in the
24-pin HTSSOP package, and the EL5824 in the 28-pin
HTSSOP package. All are specified for operation over the
-40C to +85C temperature range.

NOTE: 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.
