My needs:

A single supply op amp to act as a unity gain buffer.
Vcc = 5V, Vss = GND.
V+ = 3V, V- = Vout (as a typical buffer).
Output capable of sourcing 40mA.

Secondary considerations:

Battery application so high efficiency.

Will this op amp (**broken link removed**) do? Can you recommend a more suited one?

Thanks,

Clivest
 

since it is a battery powered application main consideration should be given to the quiscent curent after once meets ur application requirements(like GBW,bias current,offset voltage etc)......this one also looks ok if you are not concerned much with battery power....
shall try some opamps like this...
Precision Amplifier - Low Power - OPA330 - TI.com
 

Thanks for the replies. I ended up going for the TS921 in the end
