Different application fields require the development of fast preamplifiers and shaping filters to be coupled with dedicated radiation detectors. In view of fast prototyping and targeting a medium number of readout channels, we present the feasibility study, design and qualification of a large-bandwidth, opamp-based, preamplifier and shaping filter suited to equip a smart rad-hard detection system intended for the diagnostics and tagging of Radioactive Ion Beams (RIBs) at high intensity ({106 ${pps}$ or higher) The contribution illustrates the conception and design of the fast readout system and presents the detailed analysis and qualification of its performance in view of the design of a network of smart sensors, equipped with optimized frontend electronics, DAQ with Data Real-Time Management capabilities and a dedicated software layer implementing Artificial Intelligence and machine learning techniques as a tool to improve the production, transport and use of RIBs. Different prototypes have been produced and their performance experimentally compared in terms of noise, bandwidth, resolution,\,\ldots\,. both as a standalone circuit and coupled with a sample detector prototype.
