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.
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.
