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. HZIP-11A 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. *Pb-free plating product number: PA9069AL APPLICATION * Hi-Fi music centers * Stereo TV sets ORDERING INFORMATION Order Number Normal Lead Free Plating PA9069A-J11-A-T PA9069AL-J11-A-T Package Packing HZIP-11A Tube PA9069AL-J11-A-T (1)Packing Type (2)Package Type (3)Lead Plating www.unisonic.com.tw Copyright © 2005 Unisonic Technologies Co., Ltd (1) T: Tube (2) J11-A: HZIP-11A (3) Lead Free Plating, Blank: Pb/Sn 1 of 6 QW-R107-053,A PA9069A LINEAR INTEGRATED CIRCUIT PIN CONNECTION 11 10 9 8 7 6 5 4 3 2 1 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw IN+(1) IN+(1) GND IN-(2) IN+(2) -VCC MUTE OUTPUT(2) +VCC OUTPUT(1) -VCC 2 of 6 QW-R107-053,A PA9069A LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS PARAMETER SYMBOL RATING DC Supply Voltage VCC ±22 Output Power Current (internally limited) IOUT 3 Total Power Dissipation (Ta = 70°C) PD 40 Junction Temperature TJ +150 Operating Temperature TOPR 0 ~ +70 Storage and Junction Temperature TSTG -40 ~ +150 Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
