2 DESCRIPTION The is a monolithic, two-stage, differential output, wideband video amplifier. It offers fixed gains of and 4 without external components and adjustable gains from 4 to with one external resistor. The input stage has been designed so that with the addition of a few external reactive elements between the gain select terminals, the circuit can function as a high-pass, low-pass, or band-pass filter. This feature makes the circuit ideal for use as a video or pulse amplifier in communications, magnetic memories, display, video recorder systems, and floppy disk head amplifiers. Now available in an 8-pin version with fixed gain of 4 without external components and adjustable gain from 4 to with one external resistor.
