A 64-channel integrated circuit for signal readout from coordinate detectors.
A specialized integrated circuit is developed for the readout of signal from coordinate detectors of different types, including gas micro-pattern detectors and silicon micro-strip detectors. The ASIC includes 64 channels, each of those containing low-noise charge sensitive amplifier with connectable feedback capacitor and/or resistor and fast reset of the feedback capacitor. Each channel of the ASIC contains also 100 cells of the analogue memory that can be readout with 10 MHz rate through the analogue multiplexer. The pitch of input pads is 50 $mu$m and the chip size is 5x5 mm$^2$. Equivalent noise charge of the ASIC channel is about 2000 electrons with 10 pF capacitance at the input and maximal signal before saturation corresponds to 2x10$^6$ electrons. The first application for this ASIC is the detector for imaging if explosions at a synchrotron radiation beam (DIMEX), where it have to substitute old and slower APC128 ASIC. The full size electronics including 8 chips for 512 channels was assembled and tested. The results of the tests with SR beam will be shown in the presentation.
