NJM3470/3470A
FDD READ AMPLIFIER SYSTEM
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJM3470/3470A are monolithic read amplifier systems for
obtaining digital signal from floppy disk storage.
The NJM3470/3470A are designed to get pulse output signal
produced by the magnetic head amp of the input signal. They contain
amplifiers, peak detector, and pulse shape circuit. They are classified
two ranks by peak shift characteristic; NJM3470 (5%), NJM3470A (2%).
