Table 15 ALC Control
ALC SAMPLE RATE CONTROL
The register bits R27[2:0],SAMPLE_RATE must be set correctly to ensure that the ALC attack, decay
and hold times are correct for the chosen sample rate as shown in Table 15.
PEAK LIMITER
To prevent clipping when a large signal occurs just after a period of quiet, the ALC circuit includes a
limiter function. If the ADC input signal exceeds 87.5% of full scale (–1.16dB), the PGA gain is ramped
down at the maximum attack rate (as when ATK = 0000), until the signal level falls below 87.5% of full
scale. This function is automatically enabled whenever the ALC is enabled.
Note:
If ATK = 0000, then the limiter makes no difference to the operation of the ALC. It is designed to
prevent clipping when long attack times are used.
