It needs to be single supply too - I thought TLV2371 was a good pick?
Why not?
There's no such thing as a single-supply opamp, all opamps have a single supply!
Sometimes people call op-amps that operate down to the negative rail "single-supply" but that's really
sloppy terminology (invented by marketroids I bet).
Many opamps are genuinely rail-to-rail in the input circuit these days, but rail-to-rail outputs are
less common. Even a genuine rail-to-rail output opamp won't drive to the rails at anything like full power
or bandwidth - there are a few with dual output stages (bipolar and MOSFET) that do better than
the pack though. Most designs are a compromise between competing desires for low-noise, high
bandwidth, low power, high open-loop gain, low input-offset voltage and rail-to-rail output drive.
