1. Square-wave input / saturated output.

2. Evaluated at bench during product validation.

3. Guaranteed by design (intrinsically immune from any pop at mute to play and play to mute transitions)

4. The values are the ones that guarantee the correct working of the diagnostic. Since the value is strongly dependent on the

loudspeaker, we decided to target the values for the limits of open load and short load diagnostic.

5. Thermal warning junction temperature values could be changed via I2C bits IB5-d6,d7.
