The following is from the TPS65951 datasheet
5.2.7 Microphone Amplification Stage
These stages perform the single-to-differential conversion for single-ended inputs. Two programmable
gains from 0 dB to 30 dB can be set:
• Automatic level control for main microphone or submicrophone input. The gain step is 1 dB.
• Level control by register for line-in or car-kit input, or headset microphone. The gain step is 6 dB.
The amplification stage outputs are connected to the ADC input (ADC left and right).
Can ALC be turned off, while still provide manual setting of gain in 1dB intervals?
Thanks
