General Description

The EL5144C series amplifiers are voltage feedbac k, 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 v oltage range ex tend s from the nega­tive rail to within 1.5V of the positive rail. Driving a 75Ω 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 com­posite and component video applicat ions. With its voltage feedback
architecture, this amplifier can accept reactive feedback networks,
allowing them to be used in analog filtering applications These ampli­fiers 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 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
SOT23-5 package, duals in MSOP-8 and MSOP-10 packages, and
quads in a QSOP-16 package. Singl es, duals an d 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.
