N2 - A specialized integrated circuit was developed for the readout of signal from coordinate detectors of different types, including gas micro-pattern detectors and silicon microstrip detectors. The ASIC includes 64 channels, each containing a low-noise charge-sensitive amplifier with a connectable feedback capacitor and resistor, and fast reset of the feedback capacitor. Each channel of the ASIC also contains 100 cells of analogue memory where the signal can be stored at a rate of 10 MHz. The pitch of input pads is 50 μm and the chip size is 5× 5 mm2. The 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 2× 106 electrons. The first application for this ASIC is the detector for imaging of explosions at a synchrotron radiation beam (DIMEX), where it has to substitute the old and slower APC128 ASIC. The full-size electronics including 8 ASICs for 512 channels was assembled and tested.
