TA8246AHQ
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8246AHQ
Dual Audio Power Amplifier 6 W × 2 Ch
TA8246AHQ is dual 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 3 channel IC: TA8256BHQ
• Operating supply voltage range
: VCC (opr) = 10~30 V (Ta = 25°C)
