ILA1062/1062A

The supply possibilities can be increased by setting the voltage drop over the circuit VLN to a higher value be resistor

RVA connected between REG and SLPE.

VCC > 2.2V; Iline = 15mA at VLN = 4V; R1 = 620Ω; R9 = 20Ω

(1) Ip = 2.1mA. Curve (1) is valid when the receiving or when MUTE = HIGH(ILA1062), MUTE = LOW(ILA1062A).

(2) Ip = 1.7mA. Curve (2) is valid when MUTE = LOW(ILA1062), MUTE = HIGH(ILA1062A) and the receiving

amplifier is driven; Vo(rms) = 150mV, RL = 150Ω.
