Multiplexed-Input Video Amplifiers
Features
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.
• Unity or + 2-gain bandwidth of 80MHz
• 70dB off-channel isolation at 4MHz
• Directly drives high-impedance or 75Ω loads
• 0.02% and 0.02° differential gain and phase errors
• 8ns switching time
• < 100mV switching glitch
• 0.2% loaded gain error
• Compatible with ±3V to ±15V supplies
• 160mW maximum dissipation at ±5V supplies

The EL4421, EL4441, and EL4443 are internally
EL4422CS
compensated for unity-gain operation. The EL4422, EL4442ww, w.DataSheet4U.coEmL4441CN
and EL4444 are compensated for gains of +2 or more,
especially useful for driving back-matched cables.

The EL44XX multiplexed-amplifier family is fabricated with
Elantec's proprietary complementary bipolar process which
gives excellent signal symmetry and is very rugged.
