EL5624A
6-Channel Buffer with High Power V
COM
The EL5624A integrates six gamma reference buffers with a
single high power V
COM
amplifier. 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
amplifier is rated for 260mA peak output current
and also features higher slew rate (70V/s) and bandwidth
(35MHz) for use in error cancellation circuits.
The EL5624A is available in the 20-pin HTSSOP package
and is 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.
