General Description

The EL5144C 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 100

MHz. The input common mode voltage range extends from the nega-

tive rail to within 1.5V of the positive rail. Driving a 75

Ω double

terminated coaxial cable, the EL5144C series amplifiers drive to

within 150 mV of either rail. The 200 V/

µsec slew rate and 0.1% / 0.1°

differential gain / differential phase makes these parts ideal for com-

posite and component video applications. With its voltage feedback

architecture, this amplifier can accept reactive feedback networks,

allowing them to be used in analog filtering applications These ampli-

fiers will source 90 mA and sink 65 mA.

The EL5146C and EL5246C have a power-savings disable feature.

Applying a standard TTL low logic level to the CE (Chip Enable) pin

reduces the supply current to 2.6

µA within 10 nsec. Turn on time is

500 nsec, allowing true break-before-make conditions for multiplex-

ing 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

SOT23-5 package, duals in MSOP-8 and MSOP-10 packages, and

quads in a QSOP-16 package. Singles, duals and quads are also avail-

able in industry standard pinouts in SOIC and PDIP packages. All

parts operate over the industrial temperature range of -40

°C to +85°C.
