C FN7166 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. Features 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 Ordering Information PART NIMBER EL4421CN ...
