UTC8207

UTC8207 LOW FREQUENCY POWER AMPLIFIER LINEAR INTEGRATED CIRCUIT UTC8207 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 SIPH (single inline package), space merit is remarkable. Thermal shut down protection circuit is built in. FEATURE High Power: POUT=2.5W (Typ.) (VCC=9V, RL=4Ω, f=1kHz, THD=10%) POUT=4.6W (Typ.) (VCC=12V, RL=4Ω, 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 Best for supply voltage 9V, 12V Operation supply voltage range: VCC=6~15V SIP12-H-2.54 ORDERING INFORMATION Part No. UTC8207 Package SIP12-H-2.54 BLOCK DIAGRAM *2 100 F C11 3 12 1 B.S.1 C4 *1 CIN IN-1 Rf 1 47 F C1 6 100 F C10 VCC2 SW1 ­ 1000 F ­ ­ C8 VCC1 + NF 1 45 CH-1 30K ¡ RIPPLE 47 F C3 ­ 4 Bias Circuit Thermal Shut Down Protection Circuit 47 F w ­ C2 120 ¡ C5 8 45 ¡ 100 F w *1 CIN w IN-2 Rf 2 7 NF 2 C9 CH-1 10 11 ­C7 1000 F 0.15 F 30K ¡ 9 GND B.S.2 ­ ­ OUT-2 RL .D at (*1): This IC can be used without coupling capacitor (CIN).
