For a project, I need a 500mV reference.
- Relatively low cost.
- Small size. Preferably surface mount.
- Supply from 4.8V to 25V.
- Accuracy ±5% or better
- Stable over voltage (that is, it doesn't change that much with a different supply.)
I could use a diode drop but it does not satisfy condition 5, being stable over voltage.
Any suggestions appreciated!
