I am looking for a low cost ADC for a single conversion on an external trigger (ECL logic). The trigger comes exactly at the peak amplitude of the pulse (pulse-width < 20ns). I have found the AD9070 which is unfortunately an obsolete product. The digital outputs should be TTL (not ECL) but the conversion-start trigger should be ECL, otherwise (if using an ECL to TTL converter) the maximum amplitude is not hit anymore.
Input voltage range: 0 to 2.5V or 5V
no of bits: 10 or more
the speed of the ADC is not really important as we do not need to detect all pulses (only for monitoring purposes).
any suggestion is welcome!
PS: I have posted this question originally in the High-Speed ADC section, but it seems that they only have a pipelined structure which would not help me.
Here are some list of ADC that could be suitable for your application. You may also wanted to check the ADI website and do a parametric search and put in parameters on the ADC that you wanted to search. Please refer to the link below.
