Overview

XR-3471 Floppy Disk Write Amplifier GENERAL DESCRIPTION FUNCTIONAL BLOCK DIAGRAM The XR-3471 is a write amplifier designed to provide the complete interface between write data signals and tunnel and stradd Ie erase magnetic heads.
Although primarily intended for floppy disk drive systems, the XR-3471 can also be used in other magnetic media systems such as tape drives.
Write and erase currents are each externally resistor programmable.
Also included is circuitry for inner track write current compensation.
The XR-3471, available in a 20 pin DIP or small outline package, provides TTL compatible inputs.
Tunnel erase delays are determined by external reistors and capacitors.
