Small audio amplifier circuit:
This is a Small audio amplifier circuit diagram.LM1875 is a monolithic power amplifier offering. it’s 30Watts Output Power. very low distortion and high-quality performance. The LM1875 delivers 20 watts into a 4Ω or 8Ω load. ±25V supplies can make 30 watts.
Supply Range 16V-60V The LM1875 design takes advantage.
R1+R4=22k. R2+R3=1k. R5=1M. R6=10. R7=0.22/2watts. C1=2.2uf/50volt. C2=22uf/50volt. C3+C4= 2200uf/50volt. P1=330pf. P2=220n.
Must use good quality of voltage.
