Have you been use the IC above? if those who have not, IC above is used or applied to the audio power amplifier. IC processing is quite good for use on amplifier home, or room. IC used is SI1020G who have not very high output with only 20W 8 ohm impedance speakers. Supply voltage ranging from 12 volt to 23 volts. Below schematic audio amplifier with IC SI1020G Part List R1 = 100K R2 = 1R C1 = 2u2F C2 = 100uF C3 = 47uF C4 = 10uF C5 = 2200uF C6 = 47uF C7 = 100uF
