Description
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
