General Description
The EL44XX family of video multiplexed-amplifiers offers a
very quick 8 ns switching time and low glitch along with very
low video distortion The amplifiers have good gain accuracy
even when driving low-impedance loads To save power the am-
plifiers do not require heavy loading to remain stable
The EL4421 and EL4422 are two-input multiplexed amplifiers
The -inputs of the input stages are wired together and the de-
vice can be used as a pin-compatible upgrade from the
MAX453
The EL4441 and EL4442 have four inputs also with common
feedback These may be used as upgrades of the MAX454
The EL4443 and EL4444 are also 4-input multiplexed amplifi-
ers but both positive and negative inputs are wired separately
A wide variety of gain- and phase-switching circuits can be built
using independent feedback paths for each channel
The EL4421 EL4441 and EL4443 are internally compensated
for unity-gain operation The EL4422 EL4442 and EL4444 are
compensated for gains of a2 or more especially useful for driv-
ing back-matched cables
The amplifiers have an operational temperature of b40 C to
a85 C and are packaged in plastic 8- and 14-pin DIP and 8- and
14-pin SO
The EL44XX multiplexed-amplifier family is fabricated with
Elantec’s proprietary complementary bipolar process which
gives excellent signal symmetry and is very rugged
