UTC TA8207K LINEAR INTEGRATED CIRCUIT LOW FREQUENCY POWER AMPLIFIER DESCRIPTION The UTC TA8207K is an audio power IC with built-in two channels developed for portable radio cassette tape recorder with power ON/OFF switch. Because of the parts reduction and SIP (Single inline package), space merit is remarkable. Thermal shut down protection circuit is built in. FEATURES *High Power : POUT=2.5W / CH (Typ.) (Vcc=9V, RL=4, f=1KHz, THD=10%) : POUT=4.6W / CH (Typ.) (Vcc=12V, RL=4, f=1KHz, THD=10%) *Low Popping Noise at Power ON *Small Quiescent Current : ICCQ=21mA (Typ.) (Vcc=9V, VIN=0) *Soft Clip *Built-in Thermal Shut Down Protection Circuit *Bast for Supply Voltage 9V, 12V *Operation Supply Voltage Range : Vcc=6-15V FSIP-12H ABSOLUTE MAXIMUM RATINGS (Ta=25C) PARAMETER Supply Voltage Output Current (Peak / CH) Power Dissipation SYMBOL VALUE UNIT Vcc 20 V Io(peak) 2.5 A PD 12.5 W Operating Temperature Topr -20 to + 75 C Storage Temperature Tstg -55 to + 150 C UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R107-013,A UTC TA8207K LINEAR INTEGRATED CIRCUIT ELECTRICAL CHARACTERISTICS (Vcc=9V, RL=4, Rg=600, f=1kHz, Ta=25C, unless otherwise specified) PARAMETER Quiescent Current SYMBOL TEST CONDITIONS ICCQ Output Power Total Harmonic Distortion Voltage Gain MIN Vin=0 MAX UNIT 21 45 mA POUT(1) THD=10% POUT(2) Vcc=12V,THD=10% 4.6 POUT=0.4W / ch 0.2 1.0 % 45 47 dB THD GV(1) 2.0 TYP Rf=120 2.5 43 W W VOUT=0.775Vrms GV(2) Input Resistance Rf=0, VOUT=0.775Vrms RIN Output Noise Voltage VNO Rg=10k 56.5 dB 30 k 0.3 1.0 mVrms BW=20Hz ~ 20kHz Ripple Rejection Ratio R.R.

If volume slide noise occurred by input offset voltage is undesirable, it needs to use the capacitor (CIN). REMARK 2 : The condenser between the pin3 and the GND (C11) is for reducing pop noise when the power ON/OFF switch (SW1) is set to ON/OFF. UTC UNISONIC TECHNOLOGIES CO., LTD. 3 QW-R107-013,A
