S1A0071 Audio Processor for Class-D Power AMP
Digital & Analog Co., Ltd. (Rev. 1.0) -8-
6. Typical Performance
From the above measure data, the user can make an audio amplifier system with S1A0071 for several
conditions. For example, if user want to make a class D type audio amplifier with specification like as
0.1% 50W system and load impedance 4Ω. User just setup the power supply and small quality of
resistor and capacitor, FET drive and FET switch for this, and you can make a 0.1% 50W 2Channel as
faster and easily. If you want to make a audio amplifier like as THD+N <1%, 200W 2Channel system,
user can get the system quickly. Also user can make a 5.1Channel with S1A0071 3EA as easily.
