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 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.
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.
