6.31 Limiter Attack Rate (Address 29h)

6.31.1 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 65).

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 53) and DIGZC (“Digital Zero Cross” on page 53) setting unless

the respective disable bit (“Limiter Soft Ramp Disable” on page 65 or “Limiter Zero Cross Disable” on

page 66) is enabled.

6.32 ALC Enable & Attack Rate (Address 2Ah)

6.32.1 ALCx Enable

Configures the automatic level controller.

6.32.2 ALC Attack Rate

Sets the rate at which the ALC applies analog and/or digital attenuation from levels above the AMAX[2:0]

threshold (“ALC Maximum Threshold” on page 68).

Note:

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

the ANLGSFTx (“Ch. x Analog Soft Ramp” on page 49) and ANLGZCx (“Ch. x Analog Zero Cross” on

page 49) setting unless the respective disable bit (“ALCx Soft Ramp Disable” on page 55 or “ALCx Zero

Cross Disable” on page 55) is enabled.
