TA8207K

TA8207K TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8207K Low Frequency Power Amplifier 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 (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 Weight: 3.2g (typ.) 1 2002-10-30 TA8207K Maximum Ratings (Ta = 25°C) Characteristic Supply voltage Output current (peak / CH) Power dissipation Operating temperature Storage temperature Symbol VCC IO (peak) PD Topr Tstg Rating 20 2.5 12.5 -20~75 -55~150 Unit V A W °C °C Electrical Characteristics (unless otherwise specified, VCC = 9V, RL = 4Ω, Rg = 600Ω, f = 1kHz, Ta = 25°C, Rf = 120Ω) Characteristic Quiescent current Output power Total harmonic distortion Symbol ICCQ POUT (1) POUT (2) THD GV (1) Voltage gain GV (2) Input resistance Output noise voltage Ripple rejection ratio Cross talk Input offset voltage Stand-by current RIN VNO R.R.
