AGCATK
AGC Attack Time
Defined as the time required to reduce gain by 63% of the total gain reduction (one time
constant of the exponential response). Attack times are longer for low AGC threshold
levels. See Figure 12 for details.
00 = 2ms
01 = 7.2ms
10 = 31ms
11 = 123ms

AGCHLD
AGC Hold Time
The delay before the AGC release begins. The hold time counter starts whenever the sig-
nal drops below the AGC threshold and is reset by any signal that exceeds the threshold.
Set AGCHLD to enable the AGC circuit. See Figure 12 for details.
00 = AGC disabled
01 = 50ms
10 = 100ms
11 = 400ms

ANTH
Noise Gate Threshold
Gain is reduced for signals below the threshold to quiet noise. The thresholds are relative
to the ADC’s full-scale output voltage.

AGCTH
AGC Threshold
Gain is reduced when signals exceed the threshold to prevent clipping. The thresholds
are relative to the ADC’s full-scale voltage.
