UNISONIC TECHNOLOGIES CO., LTD TDA7265 Preliminary LINEAR INTEGRATED CIRCUIT 25W+25W STEREO AMPLIFIER WITH MUTE & STAND-BY DESCRIPTION The UTC TDA7265 is a stereo 25+25W class AB Dual Audio Power amplifier with mute and ST-BY control. This IC provides high output power of 25 watts per channel (at VCC=±20V, 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 =25 W/channel (Typ.) VCC= ±20V, RL = 8Ω, f =1KHz, THD = 10% * Operation supply voltage range (TA = 25°C) VCC(OPR) = ±5~±25V (RL = 8 Ω) VCC(OPR) = ±5~±18V (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.
