TA8216H

www.DataSheet4U.net TA8216H TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8216H Dual Audio Power Amplifier The TA8216H is dual audio power amplifier for consumer applications. This IC provides an output power of 13 watts per channel (at VCC = 28V, f = 1kHz, THD = 10%, RL = 8 Ω). It is suitable for power amplifier of music center. Features · · High output power: Pout = 13 W/channel (Typ.) (VCC = 28 V, RL = 8 Ω, f = 1 kHz, THD = 10%) Low noise: Vno = 0.14 mVrms (Typ.) (VCC = 28 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. Operation supply voltage range (Ta = 25°C) : VCC (opr) = 10~37 V (RL = 8 Ω) : VCC (opr) = 10~24 V (RL = 4 Ω) Weight: 4.04 g (typ.) 1 2002-02-13 www.DataSheet4U.net TA8216H Block Diagram VCC 6 Ripple Filter IN1 AMP1 5 3 1 9 VCC IN1 4 OUT1 7 RL 400 W Pre-GND 400 W 20 kW PW-GND 10 20 kW AMP2 12 RL OUT2 IN2 2 IN2 8 11 Application Information 1.
