hi there. i need to know that in op amps other than 741 in which there arent any dedicated offset adjust pins is it necessary to adjust it for smaller gains???

if it is plz post a schematic on how to adjust the offset for an op amp like LM358. and plz post a schematic. thanx

Note: i dont have EPOTs in my country so plz dont suggest solutions involving EPOTs

Feed a low current into the inverting input of a dual or quad opamp to adjust its input offset voltage.
Use a trimpot across the supply then a series resistor. I don't know what is an EPOT (a digital pot?).
