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
Rail to rail output.
Nearly 20V supply span.
So do you have any offer to us, to choose right op-amps?
thank you for your answer. There is no schematic but there is a block diagram like in attach file. Our aim is to change center frequency of the HMC899LP4 tunable filter.(Max. tunable supply +14V) We think of use high speed DAC(like AD9116) at the output of CPU. At the output of DAC, we think of use non-inverting op-amp amplifier. Frequency control input of HMC899 like in page of 9/10 at its datasheet. http://www.hittite.com/content/documents/data_sheet/hmc899lp4e.pdf
