Need high speed op-amp

for our new project, we want to change the tunable filter control voltage 0-14V in a 100ns.

 

We use DAC at the output of processor and DAC output maximum 2V and we want to amplify this signal to the nearly 14V. Also our DAC output speed rate less than 100ns. So we think of use op-amps to amplify this signal. We can use +15V/-5V supply line.

 

So we need a op-amp like that;

Signal BW nearly= 1/100ns=10MHz

Gain=7 V/V

Rail to rail output.

Nearly 20V supply span.

 

So do you have any offer to us, to choose right op-amps?
