AGC curves (output level vs. input level and THDN vs. input level) for different sampling rates, 48 KHz in Figure 3-7 and Figure 3-8, 16 KHz in Figure 3-9 and Figure 3-10 and 96 KHz in Figure 3-11 and Figure 3-12 for enhanced AGC mode.
Forward sweep: Enhanced mode behavior is same as normal mode behavior for input level sweep in the forward direction from -130 dB to -1 dB. For full scale input (0dB) also AGC output level is held at -31 dB when we are in Enhanced AGC mode.
Backward sweep: Enhanced mode behavior is same as normal mode behavior for input level sweep in the backward direction from 0 dB to -130 dB.
AGC disabled: Enhanced mode behavior is same as normal mode behavior when AGC is disabled.
