The PandaX project consists of a series of xenon-based experiments that areused to search for dark matter (DM) particles and to study the fundamentalproperties of neutrinos. The next DM experiment PandaX-4T will be using 4 tonliquid xenon in the sensitive volume, which is nearly a factor of seven largerthan that of the previous experiment PandaX-II. Due to the increasing targetmass, the sensitivity of searching for both DM and neutrinoless double-betadecay ($0\nu\beta\beta$) signals in the same detector will be significantlyimproved. However, the typical energy of interest for $0\nu\beta\beta$ signalsis at the MeV scale, which is much higher than that of most popular DM signals.In the baseline readout scheme of the photomultiplier tubes (PMTs), the dynamicrange is very limited. Signals from the majority of PMTs in the top array ofthe detector are heavily saturated at MeV energies. This deteriorates the$0\nu\beta\beta$ search sensitivity. In this paper we report a new design ofthe readout base board of the PMTs for future PandaX DM experiments and presentits improved performance on the dynamic range.
