Sharp rolloff (default)
Slow rolloff
The FLT bit allows the user to select the digital filter rolloff that is best suited to the application. Two filter rolloff
selections are available, sharp and slow. The filter responses for these selections are shown in the
Typical
Performance Curves
section of this data sheet.
