      abstract     = {MALTA2 is a depleted monolithic active pixel sensor (DMAPS)
                      designed for tracking at high ratesand typically low
                      detection threshold of ∼ 150 e−. A precise knowledge of
                      the threshold is crucialto understanding the charge
                      collection in the pixel and specifying the environment for
                      sensor application.A simple procedure is developed to
                      calibrate the threshold to unit electrons making use of
                      adedicated charge injection circuit and a Fe-55 source with
                      dominant charge deposition of 1600 e−.The injection
                      voltage is determined which corresponds to the injection
                      under Fe-55 exposure and isthe basis for charge calibration.
                      The charge injection circuit incorporates a capacitance with
                      designvalue of Cinj = 230 aF. Experimentally, the average
                      capacitance value for non-irradiated samples isfound to be
                      Cinj,exp = 257 aF. The $12\%$ divergence motivates the need
                      for the presented precisecalibration procedure, which is
                      proposed to be performed for each MALTA2 sensor. The
                      describedprocedure is feasible for any binary sensor that
                      incorporates an injection circuit.},
