100MHz Single-Supply Rail-to-Rail
Amplifiers
Features
• Rail-to-rail output swing
The EL5144 series amplifiers are voltage-feedback, high
speed, rail-to-rail amplifiers designed to operate on a single
+5V supply. They offer unity gain stability with an unloaded -
3dB bandwidth of 100MHz. The input common-mode voltage
range extends from the negative rail to within 1.5V of the
positive rail. Driving a 75Ω double terminated coaxial cable,
the EL5144 series amplifiers drive to within 150mV of either
rail. The 200V/µs slew rate and 0.1%/0.1° differential
gain/differential phase makes these parts ideal for composite
and component video applications. With their voltage-
feedback architecture, these amplifiers can accept reactive
feedback networks, allowing them to be used in analog
filtering applications These amplifiers will source 90mA and
sink 65mA.
• -3dB bandwidth = 100MHz

• Large input common-mode range 0V < V
• Diff gain/phase = 0.1%/0.1°
• Low power 35mW per amplifier
< 3.5V
CM
• Space-saving SOT23-5, MSOP8 & 10, & QSOP16
packages
• Pb-Free available (RoHS compliant)
Applications
The EL5146 and EL5246 have a power-savings disable
feature. Applying a standard TTL low logic level to the CE
(Chip Enable) pin reduces the supply current to 2.6µA within
10ns. Turn-on time is 500ns, allowing true break-before-
make conditions for multiplexing applications. Allowing the
CE pin to float or applying a high logic level will enable the
amplifier.
• Video amplifiers
• 5V analog signal processing
• Multiplexers
• Line drivers
• Portable computers
• High speed communications
• Sample & hold amplifiers
• Comparators
For applications where board space is critical, singles are
offered in a 5-pin SOT-23 package, duals in 8- and 10-pin
MSOP packages, and quads in a 16-pin QSOP package.
Singles, duals, and quads are also available in industry-
standard pinouts in SO and PDIP packages. All parts
operate over the industrial temperature range of -40°C to
+85°C.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
