TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8218AH
Audio Power Amplifier
TA8218AH
The TA8218AH is 3 channel audio amplifier for consumer applications.
This IC provides an output power of 6 watts per channel (at VCC = 20 V, f = 1kHz, THD = 10%, RL = 8 Ω). It is suitable for power amplifier of TV and home stereo.
Features
· Built-in 3ch amplifier
· High output power: Pout = 6 W/ch (Typ.)
(VCC = 20 V, RL = 8 Ω, f = 1 kHz, THD = 10%) · Low noise: Vno = 0.14 mVrms (Typ.)
