DATASHEET
EL9211, EL9212, EL9214
100MHz 100mA VCOM 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/µs. 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 -40°C to +85°C temperature
range.
