For this current project of mine , I need to amplify an ac sine wave +-0.5v(1vp-p) . It is a pure sine wave by all means and perfectly symetric + and - etc ... I wont be dealing with anything but a pure sine in the audio range .
I wish to amplify this to a maximum of +-24 volts . The opa604 .

Now I have located an op amp that seems to suit my needs , my question is the following .
Can a 50 or 100x gain of such a small signal be amplified precisely at +-24 volts with a single op amp , or do I need 2 x op amps .
Does open loop gain mean max gain of an amplifier , all datasheets have a max open loop gain and a minimum gain , but there is no talk of maximum gain in closed loop .
Also , if this op amp is specified for +-24 volts , will it do harm if I use 2 x brand new 12v batteries , I know these can reach 13.8 volts when new , so +- 27.6
thx .
