The supply possibilities can be increased by setting the voltage drop over the circuit VLN to a higher value by resistor RVA connected between REG and
SLPE.
VCC > 2.2 V; Iline = 15 mA at VLN = 4 V; R1 = 620 Ω; R9 = 20 Ω.
(1) Ip = 2.1 mA. Is valid when the receiving amplifier is not driven or when MUTE = HIGH (TEA1062), MUTE = LOW (TEA1062A).
(2) Ip = 1.7 mA. Is valid when MUTE = LOW (TEA1062), MUTE = HIGH (TEA1062A) and the receiving amplifier is driven; Vo(rms) = 150 mV,
RL = 150 Ω.
