TA8211AH
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8211AH
Dual Audio Power Amplifier
The TA8211AH is dual audio power amplifier for consumer applications. This IC provides an output power of 6 watts per channel (at VCC = 20 V, f = 1 kHz, THD = 10%, RL = 8 ). It is suitable for power amplifier of TV and home stereo.
Features
* * High output power: Pout = 6 W/channel (Typ.) (VCC = 20 V, RL = 8 , f = 1 kHz, THD = 10%) Low noise: Vno = 0.14 mVrms (Typ.) (VCC = 28 V, RL = 8 , GV = 34dB, Rg = 10 k, BW = 20 Hz~20 kHz) * * * Very few external parts Built in thermal shut down protector circuit Operating supply voltage range: VCC (opr) = 10~30 V (Ta = 25C) Weight: 4.04 g (typ.)
