Circuito interno  do lm386, a fonte de corrente  que não aparece no datasheet  fiz com  um espelho de corrente feito com os dois transistores pnp,  corrente essa que  é produzida através de uma fonte de tensão constante ,  estabilizada pelos dois diodos em série. A chave  seletora  que coloquei foi pra selecionar a fonte de corrente artificial ou a projetada para testes.

Translation: Internal circuit of lm386, the current source that does not appear in the datasheet I made with a current mirror made with the two pnp transistors, a current that is produced through a constant voltage source, stabilized by the two diodes in series. The selector switch I put was to select the artificial current source or the one designed for testing.
