EL5144, EL5146, EL5244, EL5246, EL5444

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 75

Ω 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.
