Design and performance of a multichannel multisampling analog to digital converter board for energy measurement

This paper describes a VME multichannel multisampling ADC board designed for low-energy physics experiments. To guarantee the maximum experimental flexibility the module is completely programmable through a digital signal processor and a program register accessible via VME bus. With a frequency of 40 MHz, the single channel can acquire a variable number of samples of each analog input. Besides, it is possible to use the board as a 160 MHz waveform digitizer, grouping four channels together and feeding the same analog inputs via an external fan-out.
