We are using AD8264, which will replace AD603 in our applications. I have a question about the bandwidth comments in AD8264's datasheet. It says "Small signal :235 MHz" and "Large signal: 80 MHz (1 V p-p)". We chosed AD8264 just because of its wide bandwidth. Now i was confused what's "small signal" and what's "Large signal"? How ADI defines them?
If i can only get 80 MHz bandwidth (suppose our signal is large signal, for i don't know our signal belong to samll or large signal), it will no sense to do those hardware modification (AD603's bandwidth is 90 MHz).
BTW, we use VGAx as output.
