450MHz Fixed Gain Amplifiers with Enable
The EL5108 and EL5308 are fixed gain amplifiers with a
bandwidth of 450MHz. This makes these amplifiers ideal for
today’s high speed video and monitor applications. They
feature internal gain-setting resistors and can be configured
in a gain of +1, -1 or +2. The same bandwidth is seen in both
gain-of-1 and gain-of-2 applications.
Features
• Pb-free available (RoHS compliant)
• Gain selectable (+1, -1, +2)
• 450MHz -3dB BW (AV = -1, +1, +2)
• 3.5mA supply current per amplifier
The EL5108 and EL5308 also incorporate an enable and
disable function to reduce the supply current to 25µA typical
per amplifier. Allowing the CE pin to float or applying a low
logic level will enable the amplifier.
• Single and dual supply operation, from 5V to 12V
• Available in SOT-23 packages
• 350MHz, 1.5mA product available (EL5106 and EL5306)
The EL5108 is offered in the 6 Ld SOT-23 and the industrystandard 8 Ld SOIC packages and the EL5308 is available
in the 16 Ld SOIC and 16 Ld QSOP packages. All operate
over the industrial temperature range of -40°C to +85°C.
Applications
• Battery powered equipment
• Handheld, portable devices
• Video amplifiers
• Cable drivers
• RGB amplifiers

Applications Information
Product Description
The EL5108 and EL5308 are fixed gain amplifiers that offer a
wide -3dB bandwidth of 450MHz and a low supply current of
3.5mA per amplifier. They work with supply voltages ranging
from a single 5V to 10V and they are also capable of swinging
to within 1.2V of either supply on the output. These
combinations of high bandwidth, low power, and high slew rate
make the EL5108 and EL5308 the ideal choice for many lowpower/high-bandwidth applications such as portable,
handheld, or battery-powered equipment.
For varying bandwidth and higher gains, consider the EL5166
with 1GHz on a 9mA supply current or the EL5164 with
600MHz on a 3.5mA supply current. Versions include single,
dual, and triple amp packages with 6 Ld SOT-23,
16 Ld QSOP, and 8 Ld SOIC or 16 Ld SOIC outlines.
Power Supply Bypassing and Printed Circuit Board
Layout
As with any high frequency device, good printed circuit board
layout is necessary for optimum performance. Low impedance
ground plane construction is essential. Surface mount
components are recommended, but if leaded components are
used, lead lengths should be as short as possible. The power
supply pins must be well bypassed to reduce the risk of
oscillation. The combination of a 4.7µF tantalum capacitor in
parallel with a 0.01µF capacitor has been shown to work well
when placed at each supply pin.
Disable/Power-Down
The EL5108 and EL5308 amplifiers can be disabled and
placing their outputs in a high impedance state. When
disabled, the amplifier supply current is reduced to
