Elantec Semiconductor, Inc. a leader in high-performance
analog ICs, introduced a new family of rail-to-rail high-speed amplifiers.
The EL5144C and EL5146C are designed to operate in systems running on
a single 5V supply. With rail-to-rail outputs and high drive capability,
these ICs are ideally suited to low-cost video applications, as well as
other analog processing functions. The EL5144C is available in a small
SOT23-5 package. The EL5146C is available in both 8-pin DIP and 8-pin
SO packages, and also includes a disable function. This disable reduces
supply current to 2.6 microamps and sets the outputs to a high impedance
state.
"These new amplifiers offer the perfect solution for high performance,
consumer video applications," said Michael Jennings, product line manager
for video products. "With the introduction of HDTV and DTV applications,
the requirement for high performance analog solutions is stronger than
ever. Elantec will continue to focus on this market.".
Elantec is planning future releases of dual and quad versions of the amplifiers
which will also be available in small footprint packages. Data sheets,
samples, and production quantities are available now.

A number of analog manufacturers seem to forget how lucrative it can
be to satisfy the special needs of engineers working in areas such as video;
one has to think, sometimes, that our whole industry
is focused around the massive volume markets where everything is cut-throat
and a mistake can be a major problem -- even for the largest of vendors.
The drive level from these parts is good, the use of a 5-V rail gives enough
headroom for video applications, and the 100-MHz bandwidth is more than
suitable. The use for standalone video amplifiers has dramatically increased
over the last few years and every video-oriented consumer product, or even
audio product with video switching, is using a bunch.
I also like the fact that the claims for differential
phase and gain (at 0.1 degree/0.1 %, respectively) are not inordinately
high, unlike the claims of performance that cannot be measured that I have
seen from others. Both the EL5144C and the EL5146C are in production with
the SOT-23 EL5144C priced at $0.93 in 10 k-piece lots. The EL5146C (with
the disable/high-impedance latch feature) is in either an SO-8 or DIP-8
and is priced at $1.02 in 10 k-piece lots
