·
Low noise: Vno = 0.14 mVrms (Typ.)
(VCC = 20 V, RL = 8 Ω, f = 1 kHz, THD = 10%)
Weight: 4.04 g (typ.)
(VCC = 28 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
·
Operating supply voltage range: VCC (opr) = 10~30 V (Ta = 25°C)
