Web18 de jun. de 2011 · 9. Standard opamps can't work with input voltages close to the power supply, neither V+ or V-. Same for the output: they don't go all the way to V+ or V-. What you need is a rail-to-rail I/O opamp. (There are also opamps which are only input or output rail-to-rail!). Also, most opamps want a dual supply, often minimum +5V/-5V.

Web2 de set. de 2024 · An Operational Amplifier (op-amp) is one of the most basic building blocks in circuit designs. An op-amp is typically an IC ( integrated circuit – the equivalent of many transistors, resistors, and capacitors in a single tiny chip) that amplifies signals.
