Abstract
This paper presents a new integrated circuit designed for reading signals in a silicon microstrip detector in experimental observations of fast processes on a synchrotron radiation beam. The first variants of this circuit were used in a prototype detector based on a microstrip silicon sensor and were tested on an intense synchrotron radiation beam at the VEPP-4M collider at the Institute of Nuclear Physics Siberian Branch, Russian Academy of Sciences. The results of the first measurements showed that the main objectives of this development were achieved: the temporal resolution and frame rate satisfy the initial specifications and the maximum recorded signal in a linear mode provides a significant increase in the recorded photon flux compared to the previous version of the detector based on gas technology. The main problem detected during testing of the prototype is the relatively high noise level, which will be reduced in the next version of the integrated circuit by optimizing some circuit solutions
