| 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 ). It is suitable for power amplifier of music center. Features * * High output power: Pout = 13 W/channel (Typ.) (VCC = 28 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 audio muting circuit. Built in thermal shut down protector circuit. Operation supply voltage range (Ta = 25C) : VCC (opr) = 10~37 V (RL = 8 ) : VCC (opr) = 10~24 V (RL = 4 ) Weight: 4.04 g (typ.) 1 2002-02-13 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.

Figure 2 2 2002-02-13 TA8216H 2. Muting (1) Audio muting This IC is possible to make audio muting operation by using 11 pin muting terminal. In Fig.3, the equivalent circuit in the muting circuit section is shown. By means of reducing the voltage of 11 pin down to 2.8 V or less in Fig.3, Q1 is turned ON and the base voltage of Q2 in the differential circuit fabricated with Q2 and Q3. Therefore, with the voltage reduction of 11 pin, the input circuits of dummy of input terminal and that in the doted line operate and cut-off the input signal. After muting, the bias circuit continues 1st operation and the power supply current of quiescent time. 8 pin, the capacitor terminal for reducing the pop noise can reduce the pop noise through making the time constant longer by means of inserting the capacitor externary. In the care this terminal is not used, short 8 pin with 11 pin. The voltage of 11 pin set up to 4 V or more. IC internal muting at VCC OFF When VCC = 8 V or less at VCC off, the detection circuit at VCC off is operated. And the base voltage of Q1 is reduced and the muting operation is mode.

Precaution for 4 W load resistance use Internal output current detection and protection circuit protect the IC from the influence of unusual excess current. And this function causes the interrupted sound in case of excess input voltage with VCC higher than recommended supply voltage (24V). Therefore, the power supply regulation must be fully investigated so as not to make the VCC be high than recommendation supply voltage (24V). Cautions This IC is not proof enough against a strong E-M field by CRT which may cause malfunction such as leak. Please set the IC keeping the distance from CRT. 400 W 1/5 NF 3 2002-02-13 TA8216H Standard PCB TA8216H (Bottom View) 4 2002-02-13 TA8216H Maximum Ratings (Ta = 25C) Characteristics Supply voltage Output current (Peak/ch) Power dissipation Operation temperature Storage temperature Symbol VCC IO (peak) PD (Note) Topr Tstg Rating 40 3.0 25 -20~75 -55~150 Unit V A W C C Note: Derated above Ta = 25C in the proportion of 200 mW/C.
