Notes
1.
The supply voltage for the analog audio part may have a value between 5 V and 8 V. For a supply voltage of 5 V the
maximum amplitude of in- and output signals is 1 V (RMS). For a supply voltage of 8 V the maximum amplitude of
in- and output signals is 2 V (RMS).
The value of the regulated voltage is determined by the external resistive voltage divider. The voltage range
mentioned relates to the voltage at the emitter of the external transistor. The stability of the voltage regulator loop
