350MHz Fixed Gain Amplifiers with Enable
The EL5106 and EL5306 are fixed gain amplifiers with a
bandwidth of 350MHz. 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.
With a supply current of just 1.5mA and the ability to run
from a single supply voltage from 5V to 12V, these amplifiers
are also ideal for handheld, portable or battery powered
equipment.
The EL5106 and EL5306 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.
The EL5106 is offered in the 6 Ld SOT-23 and the
industry-standard 8 Ld SOIC packages and the EL5306 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.
Features
• Pb-free available (RoHS compliant)
• Gain selectable (+1, -1, +2)
• 350MHz -3dB BW (AV = 2)
• 1.5mA supply current per amplifier
• Fast enable/disable
• Single and dual supply operation, from 5V to 12V
• Available in SOT-23 packages
• 450MHz, 3.5mA product available (EL5108 and EL5308)
Applications
• Battery powered equipment
• Handheld, portable devices
• Video amplifiers
• Cable drivers
• RGB amplifiers

Applications Information
Product Description
The EL5106 and EL5306 are fixed gain amplifier that offers
a wide -3dB bandwidth of 350MHz and a low supply current
of 1.5mA. They work with supply voltages ranging from a
single 5V to 12V and they are also capable of swinging to
within 1.2V of either supply on the output. These
combinations of high bandwidth and low power make the
EL5106 and EL5306 the ideal choice for many
low-power/high-bandwidth applications such as portable,
handheld, or battery-powered equipment.
For varying bandwidth and higher gains, consider the
EL5191 with 1GHz on a 9mA supply current or the EL5162
with 300MHz on a 4mA supply current. Versions include
single, dual, and triple amp packages with 5 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.
the positive supply. For ±5V supply, this means that the
amplifier will be enabled when CE is 2V or less, and disabled
when CE is above 4V. Although the logic levels are not
standard TTL, this choice of logic voltages allow the EL5106
and EL5306 to be enabled by tying CE to ground, even in 5V
single supply applications. The CE pin can be driven from
CMOS outputs.
Gain Setting
The EL5106 and EL5306 are built with internal feedback and
gain resistors. The internal feedback resistors have equal
value; as a result, the amplifier can be configured into gain of
+1, -1, and +2 without any external resistors. Figure 14
shows the amplifier in gain of +2 configuration. The gain
error is ±2% maximum. Figure 15 shows the amplifier in gain
of -1 configuration. For gain of +1, IN+ and IN- should be
connected together as shown in Figure 16. This
configuration avoids the effects of any parasitic capacitance
on the IN- pin. Since the internal feedback and gain resistors
change with temperature and process, external resistor
should not be used to adjust the gain settings.

Disable/Power-Down
The EL5106 and EL5306 amplifiers can be disabled placing
their output in a high impedance state. When disabled, the
amplifier supply current is reduced to
