Balanced line receivers from single supply?

[chienmort]

Is there a decent circuit for a balanced line receiver powered by a single positive supply?

Look at the TI DRV632 (3.3V supply) and DRV603 (5.0V supply) - they can be configured as line receivers

You can change any circuit that uses dual supplies to a single supply by adding coupling capacitors and some way to bias the input.
