High current drive op-amp?

I'm looking for a high DC current drive op-amp with low input bias current and low noise!

I need to drive up to 300 mA DC into approx 30 Ohm load. I have considered the AD8397, the datasheet says it can drive 310 mA AC current at 10 V p-p @ 100 kHz but I will be driving a DC load.

Any suggestions?

I may be able to select a smaller load and go with a lower supply op-amp if required. Low input bias current (< 1µA) is essential.
