Amplifiers  
Features  
COM  
The EL9211, EL9212, and EL9214 feature 1, 2, and 4  
channel high power output amplifiers. They are designed  
• 1, 2, and 4 channel versions  
• 130MHz -3dB bandwidth  
• 115V/µs slew rate  
primarily for generation of V  
voltages in TFT-LCD  
COM  
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.  
• 300mA peak output current  
• Supply voltage from 5V to 13.5V  
• Low supply current - <2.4mA per channel  
• Pb-free available (RoHS compliant)  
All units are available in Pb-free packaging only and are  
specified for operation over the -40°C to +85°C 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-020C.  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

EL9211, EL9212, EL9214  
Unused Amplifiers  
Application Information  
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.  
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 general-  
purpose 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.  
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.  
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.  
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.
