TA8258HQ TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8258HQ Dual Audio Power Amplifier The TA8258HQ is dual audio power amplifier for consumer applications. This IC provides an output power of 20 watts per channel (at VCC = 37 V, f = 1kHz, THD = 10%, RL = 8 Ω). It is suitable for power amplifier of music center. Features • • • • • • • • High output power: Pout = 20 W/channel (Typ.) (VCC = 37 V, RL = 8 Ω, f = 1 kHz, THD = 10%) Low noise: Vno = 0.14 mVrms (Typ.) (VCC = 37 V, RL = 8 Ω, GV = 34dB, Rg = 10 kΩ, BW = 20 Hz~20 kHz) Very few external parts. Built in audio muting circuit. Built in thermal shut down protector circuit. Built in output shifted to GND protection circuit. (AC short) Available for using same PCB layout wit [ ... ]
