I am currently testing the AD8369 VGA. 180MHz & 250MHz are the frequencies I am concerned with. The IC is going into saturation above -27dB. I would like to know the maximum & minimum input levels which can be tolerated by this device. As the current design needs a digitally controlled VGA which can cater to an input signal level between -10dB & 5dB, can you suggest an alternative VGA IC?
