TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8229K
Low Frequency Power Amplifier
TA8229K is an audio power IC with built-in two channels
developed for portable radio cassette tape recorder with power
ON/OFF switch. Thermal shut down protection circuit is built in.
Features
· High power
: Pout (1) = 2.5 W (typ.)
(VCC = 9 V, RL = 4 , f = 1 kHz, THD = 10%)
Pout (2) = 4.6 W (typ.)
(VCC = 12 V, RL = 3 , f = 1 kHz, THD = 10%)
· Low popping noise at power ON
· Small quiescent current
: ICCQ = 21 mA (typ.) (VCC = 15 V, Vin = 0)
· Soft clip
· Built-in thermal shut down protection circuit
· Best for supply voltage 9 V, 12 V
· Operation supply voltage range: VCC (opr) = 6~15 V (Ta = 25°C)
Weight: 3.9 g (typ.)

Test Circuit
TA8229K
*1: This IC can be used without coupling capacitor (CIN). If volume slide noise occurred by input offset voltage
is undesirable, it needs to use the capacitor (CIN).
*2: The condenser between the pin 8 and the GND (C11) is for reducing POP noise when the power ON/OFF
switch (SW1) is set to ON/OFF.
