Are there any single supply OP amps with negative supply voltage?
The term 'single supply op-amp' is rather outdated now.

In the bad old days, op-amps had both an input range (common mode voltage, or VCM) and an output range that stopped a volt or three short of both rails. As many applications required operation around ground, they had to have both positive and negative rails.

Now, there are many amplifiers built with an input range that includes both rails, and whose output range goes very close to the rails, at least at low current. These are full rail-to-rail, or R2R amplifiers. If you want to use them directly with signals around ground, you still need a positive and a negative rail.

For AC application like audio, you can AC couple, so the circuit inputs and outputs can be around ground, but the amplifier works correctly within its rails, whatever they are.

For DC applications, while level shifting is still a possibility, it's far more convenient when operating with positive voltages close to ground, to use an amplifier whose VCM includes the negative supply, and which can drive close to the negative supply. Then, the negative supply can be connected to ground.

Amplifiers like the popular LM324 have a VCM and an output that includes the negative rail, so can be used in this way. When people design such circuits to interface with logic, or car electrics, they tend to think in the few positive volts above ground, and not worry too much that they can't get a full positive output, or that the VCM stops 2v short of the positive rail. 

This is the 'single supply op-amp'. Connect the negative rail to ground. Use it near ground, as long as the signal is still strictly positive. Don't go negative. Don't use it near the positive rail, but you didn't want to do that anyway!

Summary

To operate either side of ground, use positive and negative supplies.

To operate close to ground but never below, use an amplifier whose VCM and output includes the negative rail, which you ground.

To operate close to both rails, use a full R2R amplifier, whether the negative rail is grounded, or sent to a more negative supply.
