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.
• Unity or + 2-gain bandwidth of 80MHz
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.
• < 100mV switching glitch
The EL4441 and EL4442 have four inputs, also with
common feedback. These may be used as upgrades of the
MAX454.
• 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
• 0.2% loaded gain error
• Compatible with ±3V to ±15V supplies
• 160mW maximum dissipation at ±5V supplies
Ordering Information
PART
NIMBER
The EL44XX multiplexed-amplifier family is fabricated with
Elantec's proprietary complementary bipolar process which
gives excellent signal symmetry and is very rugged.

EL4422CN
The amplifiers have an operational temperature of -40°C to
+85°C and are packaged in plastic 8- and 14-pin DIP and 8and 14-pin SO.
PACKAGE
EL4421CS
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.
TEMP. RANGE
EL4421CN
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.
