ADC2318 is ADC module for MCA.Constituited by Exclusive use of nuclear
detective peak detect circuit and ADC. this product have Crucial spec requested
to MCA, such as "unmatched accuracy for peak detection" and "fine
differencial nonlinerity". those specs are confirmed by pulser at
1 channel.(pulse 1ch.jpg)。
tempreture stability is customed by 100ppm to 10ppm.
requested power has been developed to more ecological as 50ｍA to 18ｍA.and
half sized.
test report and inspection report is able to order optionaly.

2318-5.jpg After the peakdetect, start AD convertion immediately. convertion done
in
about 600nSec (2ch light blue) and reset the peakhold. then, allow
next input.
2318-6.jpg AD convertion data processing time it self at MCA is 300nSec.
so if peaking time is 0.6uSec dead time of MCA can be ignored.
○ Temperature stability was 100ppm but 10ppm now.
○ Power suply required has minimized by 50ｍA to 18ｍA.
○ and SIZE!
