PA9069A
14W+14W STEREO AMPLIFIER
WITH MUTE & STAND-BY
DESCRIPTION
The UTC
PA9069A
is a stereo 14+14W class AB Dual Audio
Power amplifier with mute and ST-BY control. This IC provides high
output power of 14 watts per channel (at V
CC
= ±16V, f =1KHz,
THD = 10%, R
L
= 8
Ω).
It has low I
Q
at stand-by mode and no POP
at turn ON or OFF.
