Multiplexed-Input Video Amplifiers
The EL44XX family of video
multiplexed-amplifiers offers a very
quick 8ns 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 amplifiers 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 device 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
amplifiers, 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 +2 or more,
especially useful for driving back-matched cables.
The amplifiers have an operational temperature of -40°C to
+85°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.
