NTE3470

NTE3470 Integrated Circuit Floppy Disk Read Amplifier System Description: The NTE3470 is a monolithic READ Amplifier System for obtaining digital information from floppy disk storage. It is designed to accept the differential AC signal produced by the magnetic head and produce a digital output pulse that corresponds to each peak of the input signal. The gain stage amplifies the input waveform and applies it to an external filter network, enabling the active differentiator and time domain filter to produce the desired output. Features: D Combines All the Active Circuitry to Perform the Floppy Disk Read Amplifier Function in One Circuit D Improved (Positive) Gain TC and Tolerance D Improved Input Common Mode Absolute Maximum Ratings: (TA = +25°C, Note 1 unless otherwise specified) Power Supply Voltage (Pin11), VCC1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7V Power Supply Voltage (Pin18), VCC2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16V Input Voltage (Pin1 and Pin2), VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.2 to +7.0V Output Voltage (Pin10), VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.2 to +7.0V Operating Ambient Temperature Range, TA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0° to +70°C Operating Junction Temperature...
