TA8218AH

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.) Weight: 9.8 g (typ.) (VCC = 20 V, RL = 8 Ω, GV = 34dB, Rg = 10 kΩ, BW = 20 Hz~20 kHz) · Built in audio muting circuit (Active → Low) : Main amp/surround amp independent control. · Built in various protection circuits Protection circuit: Thermal shut down, over voltage, Out → GND short. · Operation supply voltage range: VCC (opr) = 10~30 V (Ta = 25°C) 1 2002-02-13 Block Diagram TA8218AH INPUT1 (MAIN) INPUT2 (MAIN) INPUT3 (SURROUND) 8 RIPPLE FILTER 6 Amp 1 7 400 W 200 W 3 Pre-GND 20 kW 1 400 W 2 Amp 2 9 VCC OUT1 10 PW-GND 13 OUT2 17 16 MUTE (MAIN) MUTING 11 MUTE (SURROUND) 5 Amp 3 4 400 W 20 kW 15 12 OUT3 14 VCC RL RL RL Cautions This IC is not proof enough against a strong E-M field by CRT which may cause malfunction such as leak.
