Hello once again!
I'm reading about Texas Instrument's Single Supply Opamp Circuits reference guide. I was wondering if there is a way to create a half-supply voltage reference that is completely dependent on the input supply voltage.
The reason why I'm asking is because if the supply voltage drops, then I want the voltage reference to also take this into account. For example, if I start at 5V, then my initial half-supply voltage would be
2.5V. But in time if the supply voltage drops to 4.8V, then I want the half-supply to automatically adjust to 2.4V.Any recommendations?
Thanks!
