You could tie the output to the inverting input, and tie the non-inverting input to either rail. goty orchestra

"Web11 de out. de 2008 · I'd strongly recommend this for CMOS op-amps with a class A output stage which will use more power if the output sits between the rails as both output transistors will be on simultaniously. I've heard that some op-amps don't like this and prefer to be configured as a voltage follower with the input connected to 0V. " - Op amp unused inputs

Web1 de abr. de 2024 · In some circuits with positive feedback (e.g., a non-inverting Schmitt trigger ), the op-amp is driven from the side of the non-inverting input; that is why the circuit is non-inverting. Here the unused inverting input is fixed (grounded). Another example of such circuit but without positive feedback can be a non-inverting op-amp comparator. WebThe input offset voltage of operational amplifiers (op amps) arises from unavoidable mismatches in the differential input stage of the op-amp circuit caused by mismatched …

WebUnused amplifier inputs are one of the important exceptions. As we saw in RAQ Issue 46 3, grounding an unused amplifier's inputs may increase its current consumption, so the best policy here, and often the only safe one, is to connect the amplifier as a buffer, tying the input to a potential somewhere between the supply rails.
