A high resolution 14-bit ADC for Gammasphere Project

Conference ·
OSTI ID:10149927
A system of 110 high performance A/D converters, required for the Gammasphere Project at the Lawrence Berkeley Laboratory, is described. The ADCs are compact, linear ({plus_minus})0.006% integral, {plus_minus}0.5% differential, with a conversion deadtime of 5.3 {mu}s and channel profile flatness of 50% over a 13-bit range. The converter is based on a new low power (0.25 W), low cost, monolithic high speed sampling ADC, exibiting a very high stability and no missing codes over the entire 16-bit range. Differential linearity was achieved by applying the ``Gatti method``, covering a 8-bit range. Measured data and methods of testing the ADC are also resented.
