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!
