I have an application for a 0 to 5 V signal output buffer for industrial control. Load is about 1 k to ground. In this industrial control application, power is a 24 V single supply.
What amp can anyone recommend that has the lowest output-low voltage for this kind of application? I've checked out a couple of the rail-to-rail precision amps like OPA340 but they mostly have 5.5V maximum supply rails, so they are non-starters with my 24 V rail.
I know that the "right" answer might be to create a negative rail, but I am trying to do the best I can with a simple single supply buffer.
