      abstract     = {This contribution describes a monolithic digital silicon
                      photomultiplier (dSiPM), designed and characterized at DESY.
                      It consists of an array of single photon avalanche diodes
                      (SPADs) arranged in a 32 x 32-pixel matrix at 70 μm pitch,
                      with embedded CMOS circuitry for on-chip signal processing.
                      The dSiPM is designed in LFoundry’s 150-nm CMOS process
                      employing a fully characterized SPAD design provided by the
                      manufacturer. It enables in-pixel sensor-signal digitization
                      and masking, and provides the full hit map and time stamping
                      at 3-MHz frame rate with a resolution better than 100 ps.
                      Especially the availability of highly granular position
                      information will be beneficial for applications like the
                      readout of scintillating fibers, or the detection of
                      minimum-ionizing particles (MIPs). Several measurements were
                      carried out in the laboratory and at the DESY II test-beam
                      facility using the Caribou readout system. The dark-count
                      rate as function of the overvoltage and temperature, the TDC
                      resolution, as well as their differential and integral
                      nonlinearity are presented. The dSiPM was used to identify
                      MIPs in the test beam and has demonstrated a detection
                      efficiency of 30 $\%,$ limited by the fill factor. Comparing
                      the time measurements of two dSiPMs installed at the test
                      beam, show a time resolution on the order of 50 ps.},
