Features
The EL9211, EL9212, and EL9214 feature 1, 2, and 4
channel high power output amplifiers. They are designed
primarily for generation of VCOM 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.
• 1, 2, and 4 channel versions
All units are available in Pb-free packaging only and are
specified for operation over the -40°C to +85°C temperature
range.

EL9211, EL9212, EL9214
Application Information
Product Description
The EL9211, EL9212, and EL9214 voltage feedback
amplifiers are fabricated using a high voltage CMOS
process. They exhibit rail-to-rail input and output capability,
are unity gain stable and have low power consumption
(2.4mA per amplifier). These features make the EL9211,
EL9212, and EL9214 ideal for a wide range of generalpurpose applications. Connected in voltage follower mode
and driving a load of 10K, the EL9211, EL9212, and EL9214
have a -3dB bandwidth of 130MHz while maintaining a
115V/µs slew rate. The EL9211 is a single amplifier, EL9212
is a dual amplifier, and EL9214 is a quad amplifier.
Operating Voltage, Input, and Output
The EL9211, EL9212, and EL9214 are specified with a
single nominal supply voltage from 5V to 13.5V or a split
supply with its total range from 5V to 13.5V. Most EL9211,
EL9212, and EL9214 specifications are stable over both the
full supply range and operating temperatures of -40°C to
+85°C. Parameter variations with operating voltage and/or
temperature are shown in the typical performance curves.
Unused Amplifiers
It is recommended that any unused amplifiers in a dual and
quad package be configured as a unity gain follower. The
inverting input should be directly connected to the output
and the non-inverting input tied to the ground plane.
Power Supply Bypassing and Printed Circuit
Board Layout
The EL9211, EL9212, and EL9214 can provide gain at high
frequency. As with any high-frequency device, good printed
circuit board layout is necessary for optimum performance.
Ground plane construction is highly recommended, lead
lengths should be as short as possible and the power supply
pins must be well bypassed to reduce the risk of oscillation.
For normal single supply operation, where the -VS pin is
connected to ground, a 0.1µF ceramic capacitor should be
placed from +VS to pin and -VS to pin. A 4.7µF tantalum
capacitor should then be connected in parallel, placed in the
region of the amplifier. One 4.7µF capacitor may be used for
multiple devices. This same capacitor combination should be
placed at each supply pin to ground if split supplies are to be
used.
Short Circuit Current Limit
The EL9211, EL9212, and EL9214 will limit the short circuit
current to 300mA if the output is directly shorted to the
positive or negative supply. If an output is shorted
indefinitely, the power dissipation could easily increase such
that the device may be damaged. Maximum reliability is
maintained if the output continuous current never exceeds
±65mA. This limit is set by the design of the internal metal
interconnects.
Output Phase Reversal
The EL9211, EL9212, and EL9214 are immune to phase
reversal as long as the input voltage is limited from
-VS -0.5V to +VS +0.5V. Although the device's output will not
change phase, the input's over-voltage should be avoided. If
an input voltage exceeds supply voltage by more than 0.6V,
electrostatic protection diodes placed in the input stage of
the device begin to conduct and over-voltage damage could
occur.
