TA8256BH

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8256BH Audio Power Amplifier 6 W × 3 Ch TA8256BH TA8256BH is 3 channel audio power amplifier for Consumer applications. This IC provides an output power of 6 watts per channel (at VCC = 20 V, f = 1 kHz, THD = 10%, RL = 8 Ω). It is suitable for power amplifier of TV and home Stereo. Features · High output power: Pout = 6 W (Typ.) (VCC = 20 V、RL = 8 Ω、f = 1 kHz、THD = 10%) · Built-in audio muting circuit. · NF terminal capacitor less Weight: 4.04 g (typ.) : Fixed gain (Gv = 34dB), needless external capacitor. · Protectors : Thermal shut down protection circuit, over voltage protection circuit · Low poping noise · High THD ratio · High input dynamic range · Available for using same PCB layout with 2 channel IC: TA8246AH · Operating supply voltage range : VCC (opr) = 10~30 V (Ta = 25°C) 1 2002-02-13 Block Diagram INPUT1 INPUT2 INPUT3 6 RIPPLE FILTER 4 kW 4 Amp 1 30 kW 350 W 20 kW 9 8 OUT1 2.1 V 3 Pre-GND V18 PW-GND 10 350 W 4 kW 2 20 kW Amp 2 12 OUT2 30 kW 30 kW 4 kW 1 Amp 3 11 OUT3 350 W 20 kW 5 MUTE SW 7 MUTE T.C.
