EL9211, EL9212, EL9214
100MHz 100mA V
COM
Amplifiers
The EL9211, EL9212, and EL9214 feature 1, 2, and 4
channel high power output amplifiers. They are designed
primarily for generation of V
COM
voltages in TFT-LCD
applications. Each amplifier features a -3dB bandwidth of
130MHz with slew rates of 115V/s. Each device comes in a
thermal package and can drive 300mA peak per output.
All units are available in Pb-free packaging only and are
specified for operation over the -40C to +85C temperature
range.
Features
1, 2, and 4 channel versions
130MHz -3dB bandwidth
115V/s slew rate
300mA peak output current
Supply voltage from 5V to 13.5V
Low supply current - <2.4mA per channel
Pb-free available (RoHS compliant)
Applications
TFT-LCD V
COM
supply
Electronics notebooks
Computer monitors
Electronics games

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-020C.
