A front-end readout system with a large dynamic range is required for the high-granularity crystal electromagnetic calorimeter (ECAL) at future Higgs factories. A new commercially available ASIC, MPT2321, which offers a significantly large dynamic range for the readout of the silicon photomultiplier (SiPM), has been tested in the laboratory and at a test beam facility. The fundamental performance metrics have been characterised, including response linearity, inter-calibration factor and noise performance. To quantitatively assess the dynamic range of the chip and evaluate its feasibility for SiPM readout in high-granularity crystal ECAL, a beamtest was conducted using scintillating crystals exposed to electron beams. Beamtest results showed that the chip exhibits a promising performance in terms of a good signal-to-noise ratio and a relatively large dynamic range.
