UNISONIC TECHNOLOGIES CO., LTD 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 VCC = 16V, f =1KHz, THD = 10%, RL = 8 ). It has low IQ at stand-by mode and no POP at turn ON or OFF.
LINEAR INTEGRATED CIRCUIT
HZIP-11A
