Dual Audio OP Amp LME49722 http://www.national.com/pf/LM/LME49722.html
Data Sheet LME 49722 http://www.national.com/ds.cgi/LM/LME49722.pdf

The LME49722 has a wide supply range of ±2.5V to ±18V. Over this supply range the LME49722 maintains excellent common-mode and power supply rejection, and low input bias current. This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF with gain value greater than 2. Directly interchangeable with LME49720, LM4562 and LME49860 for similar operating voltages.
