Multiplexed-Input Video Amplifiers
Features
Unity or a 2-gain bandwidth of 80 MHz 70 dB off-channel isolation at 4 MHz Directly drives high-impedance or 75X loads 02% and 02 differential gain and phase errors 8 ns switching time k 100 mV switching glitch 0 2% loaded gain error Compatible with g 3V to g 15V supplies 160 mW maximum dissipation at g 5V supplies
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 amT plifiers do not require heavy loading to remain stable The EL4421 and EL4422 are two-input multiplexed amplifiers he -inputs of the input stages are wired together and the device can be used as a pin-compatible upgrade from the T MAX453 he EL4441 and EL4442 have four inputs also with common T feedback These may be used as upgrades of the MAX454 he EL4443 and EL4444 are also 4-input multiplexed amplifiA ers but both positive and negative inputs are wired separately wide variety of gain- and phase-switching circuits can be built T using independent feedback paths for each channel he EL4421 EL4441 and EL4443 are internally compensated for unity-gain operation The EL4422 EL4442 and EL4444 are compensated for gains of a 2 or more especially useful for drivT ing back-matched cables he amplifiers have an operational temperature of b 40 C to C and are packaged in plastic 8- and 14-pin DIP and 8- and T 14-pin SO
