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 75double
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.
