curve (a) is valid when the receiving amplifier is not driven or when MUTE =LOW
(UTC TEA1062 is
HIGH)
.curve(b) is valid when MUTE=HIGH
(UTC TEA1062 is LOW)
and the receiving amplifier is
driven;Vo(rms)=150mV,R
L
=150
.The supply possibilities can be increased simply by setting the voltage drop
over the circuit V
LN
to a high value by means of resistor R
VA
connected between REG and SLPE.
