XR-2247A Overview
FUNCTIONAL BLOCK DIAGRAM The XR-2247/2247A is a write amplifier designed to provide the plete interface between write data signals and tunnel-erase magnetic heads. Although primarily intended for floppy disk drive systems, the XR-22471 2247A can also be used in other magnetic media systems such as tape drives. To minimize external part count for dual head systems, plete head switching is does internally with...
