A quanto dice, pare che sia una la configurazione idonea (figura 1), mentre le altre vanno scartate;
pero non mi torna una cosa: riguardo a questa configurazione idonea dice
"If the circuit has dual supplies, the two resistors are not necessary and simply grounding the non-inverting terminal is sufficient. Additionally, the non-inverting terminal can be connected to another voltage elsewhere in the circuit that is within the input common-mode voltage range of the device, thereby eliminating the need for the two resistors in Figure 1."
Questa "another voltage elesewhere" non puo' essere V-?
thanks!
