Multi-Channel Buffers
Features
• Multiple gamma buffers
- 6 channels (EL5129)
- 10 channels (EL5329)
The EL5129 and EL5329 integrate multiple gamma buffers
and a single V
buffer for use in large panel LCD
COM
displays of 10” and greater. The EL5129 integrates 6 gamma
channels and the EL5329 integrates 10 gamma channels.
Half of the gamma channels in each device are designed to
swing to the upper supply rail, with the other half designed to
swing to the lower rail. The output capability of each channel
is 10mA continuous, with 120mA peak. The gamma buffers
feature a 10MHz 3dB bandwidth specification and a 9V/µs
slew rate.
• Single V
COM
amplifier
• Low supply current
- 3.5mA (EL5129)
- 5.5mA (EL5329)
• For higher speed or higher output power, see the EL5x24
family
The V
amplifier is designed to swing from rail to rail. The
COM
output current capability of the V
• Pb-free available (RoHS compliant)
in the EL5129 and
COM
EL5329 is 30mA continuous, 150mA peak and a slew rate of
10V/µs.
Applications
• TFT-LCD monitors
Ordering Information
• LCD televisions
TAPE &
• Industrial flat panel displays

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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.

Description of Operation and Application
Information
Product Description
The maximum power dissipation allowed in a package is
determined according to:
The EL5129 and EL5329 are fabricated using a high voltage
CMOS process. They exhibit rail to rail input and output
capability and have very low power consumption. When
driving a load of 10K and 12pF, the buffers have a

• T
• T

JMAX
Input, Output, and Supply Voltage Range
AMAX
The EL5129 and EL5329 are specified with a single nominal
supply voltage from 5V to 15V or a split supply with its total
range from 5V to 15V. Correct operation is guaranteed for a
supply range from 4.5V to 16.5V.
• θ = Thermal resistance of the package
JA
• P
DMAX
= Maximum power dissipation in the package
The maximum power dissipation actually produced by an IC
is the total quiescent supply current times the total power
supply voltage, plus the power in the IC due to the loads, or:
The input common-mode voltage range of the EL5129 and
EL5329 within 500mV beyond the supply rails. The output
swings of the buffers and V
amplifier typically extend to

Power Supply Bypassing and Printed Circuit
Board Layout
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 V - pin is
S
connected to ground, one 0.1µF ceramic capacitor should be
placed from the V + pin to ground. A 4.7µF tantalum
S
capacitor should then be connected from the V + pin to
S
ground. 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.
Important Note: The metal plane used for heat sinking of
the device is electrically connected to the negative
supply potential (V -). If V - is tied to ground, the

S
thermal pad can be connected to ground. Otherwise, the
thermal pad must be isolated from any other power
planes.
