CXA1720Q - Read/Write Amplifier (with Built-in Filters) for FDDs

General Description

The CXA1720Q is an IC for use with floppy disk drives, and contains a Read circuit (with built-in filters), Write circuit, Erase circuit, and supply voltage detection circuit, all into a single chip.

Key Features

  • Single 5 V power supply.
  • Filter system can be switched among four modes: 1M/2M, and inner track/outer track. This allows for a significant reduction in the number of external parts such as differentiator constants, low-pass filters, and switches. (Compared with conventional Sony products, the number of parts has been reduced by one-half. ).
  • Filter characteristics can be customized.
  • Low pre-amplifier input conversion noise voltage of 2.0 nV/ √ Hz (typ. ) keeps.
