UNISONIC TECHNOLOGIES CO., LTD PA9069A LINEAR INTEGRATED CIRCUIT 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 Ω). It has low IQ at stand-by mode and no POP at turn ON or OFF. FEATURES * High output power: POUT =14 W/channel (Typ.) VCC= ±16V, RL = 8Ω, f =1KHz, THD = 10% * Operation supply voltage range (Ta = 25°C) VCC(OPR) = ±5~±20V (RL = 8 Ω) VCC(OPR) = ±5~±15V (RL = 4 Ω) * Split supply * Built in overload protection circuit. * Built in thermal shut down protector circuit. * Built in audio muting circuit (POP free) * Built in standby circuit.
