UTC8207
LINEAR INTEGRATED CIRCUIT
LOW FREQUENCY POWER
AMPLIFIER
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

.D (*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).
a (*2): The condenser between the pin and the GND (C11) is for reducing pop noise when the power ON / OFF
taswitch (SW1) is set to ON/OFF.
