AGC CONTROL
without deteriorating the audio quality.
AGC CONTROL REGISTER (ACNT)
THD(2−0): Define the maximum distortion level acceptable in non−clipping mode.
PWR(2−0): Define the maximum peak voltage in output of the amplifier in case of limiter mode.
NC/L: Non−clipping mode and limiter mode selection bit.
•
•
AGCE : Activate or disable the AGC function bit.
•
•
The AGC function is to protect the speaker from damage due to exceeded output power. The function limits the output power
This register allows controlling the AGC setup.
0 = Non−clipping mode.
1 = Limiter mode.
0 = AGC disable.
1 = AGC enable.
