NE592
DESCRIPTION
The NE592 is a monolithic, two-stage, differential output, wideband
video amplifier. It offers fixed gains of 100 and 400 without external
components and adjustable gains from 400 to 0 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 400 without
external components and adjustable gain from 400 to 0 with one
external resistor.
