curve (a) is valid when the receiving amplifier is not driven or when MUTE =LOW (UTC TEA1062N is HIGH) .curve(b)

is valid when MUTE=HIGH(UTC TEA1062N is LOW) and the receiving amplifier is driven;

Vo(rms)=150mV,RL=150Ω.The supply possibilities can be increased simply by setting the voltage drop over the

circuit VLN to a high value by means of resistor RVA connected between REG and SLPE.
