pwede sir! yung shema kasi mismo sa Company eh shortcut lang yun!

for output stage (transistor) kailangan mo ng pre/ driver stage (transistor)

for lme49830 and lme49810 pwede direct mosfet dahil masmataas yung output current nila

 you may try 2SA1216 and 2sc2922, but masmahal pero masmataas naman power at masmaganda ang heat dissipation kasi masmalaki yung surface nya (MT-200)
