We want to choose two high-speed amplifiers, one for ADC board(four channel input)  and the other for DAC board(four channel output).


(1)  input signals of ADC boad are single-ended,  the frequency of  input signals is 0~100MHz,  amplitude of input signals is -2.0V~+2.0V, the gain flatness is not more than 0.2dB;

input for ADC chip is differential, input common-mode voltage of ADC chip is around 1.0V, analog input span is around 1.6Vpp.


(2)  output signals of DAC board is single-ended and drive 50Ohm load, the frequency of output signal is 0~100MHz, amplitude of output signals is -2.0V~+2.0V, the gain flatness is not more than 0.2dB.


what amplifiers from ADI can meet the requirement?


Thank you!
