100MHz Single-Supply Rail-to-Rail
Amplifiers
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 75double 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.
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.
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.
