3, and works as follows: The input goes through a 10 kilohm resistor, then to the high side of a 10 kilohm, 10-turn trim pot, which sets the input (clip) level. From there, the audio goes to half of a ...

The ADC’s reference voltage can be used for the clipping reference if available. When the input voltage is below the reference, U1’s output is driven to the positive rail and D1 is reverse ...

Suppose you have a receiver that can deliver 1 volt RMS from its preamplifier outputs before clipping; if you pair this receiver with a high powered amplifier expecting a huge boost in headroom, you ...

Let’s assume that the volume is turned up to the point just before clipping kicks in – where the amplifier is pushing out its maximum voltage without distortion. This clipping point fixes the ...

The preamplifier is designed for dynamic mics. To pad the clipping voltage level of the microphone (1.25 Vrms) down to the clipping voltage level of the preamplifier (20 mVrms) requires a 35-dB pad!

A signal that's large enough to clip the ADC would in turn receive maximum gain compression. For this example, keep the MDAC gain low enough to allow the full input-voltage range without clipping ...
