FLT
Digital Filter Roll-Off Control
Default Value: 0
FLT = 0
FLT = 1
Sharp Roll-Off (default)
Slow Roll-Off
The FLT bit allows the user to select the digital filter roll-off that is best suited to their application. Two
filter roll-off selections are available: Sharp or Slow. The filter responses for these selections are shown
in the Typical Performance Curves section of this data sheet.
