It is suitable for power amplifier of TV.
Features
· High output power: Pout = 6 W (Typ.)
(VCC = 20 V, RL = 8 Ω, f = 1 kHz, THD = 10%)
· Low noise: Vno = 0.14 mVrms (Typ.)
(VCC = 20 V, RL = 8 Ω, GV = 34dB, Rg = 10 kΩ,
BW = 20 Hz~20 kHz)
· Very few external parts
· Built in thermal shut down protector circuit
· Operation supply voltage range: VCC (opr) = 10~30 V (Ta = 25°C)
