6.39.1 Limiter Attack Rate

Sets the rate at which the limiter applies digital attenuation from levels above the MAX[2:0] threshold

(“Limiter Maximum Threshold” on page 85).

Note: The limiter attack rate is user-selectable but is also a function of the sampling frequency, Fs, and

the DIGSFT (“Digital Soft Ramp” on page 64) setting unless the disable bit (“Limiter Soft Ramp Disable”

on page 82) is enabled.
