Abstract
The development of a multichannel application-specific integrated circuit (ASIC) for registration and processing of signals from microstrip sensors in synchrotron radiation coordinate detectors developed at the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences to equip the experimental stations of the SKIF is presented. The ASIC contains 64 independent photon registration channels with four energy separation thresholds. The range of registered energies is from 3 to 60 keV. The structure and basic parameters of the electronics of the registration channel for direct photon counting are described in detail.
