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 75W 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.
Features
• Rail-to-rail output swing
• -3dB bandwidth = 100MHz
• Single-supply +5V operation
• Power-down to 2.6µA
• Large input common-mode range 0V < V
• Diff gain/phase = 0.1%/0.1°
< 3.5V
CM
• Low power 35mW per amplifier
• Space-saving SOT23-5, 8 Ld MSOP and 10 Ld MSOP,
and 16 Ld QSOP packages
• Pb-Free available (RoHS compliant)
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.
Applications
• Video amplifiers
• 5V analog signal processing
• Multiplexers
For applications where board space is critical, singles are
offered in a 5 Ld SOT-23 package, duals in 8 Ld and 10 Ld
MSOP packages, and quads in a 16 Ld 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.
• Line drivers
• Portable computers
• High speed communications
• Sample and hold amplifiers
• Comparators
