The Mod. V265 is a 1-unit wide VME 6U module with 8 charge integrating negative inputs (positive on request).
The unit is ideally suited for large detectors in applications like electromagnetic and hadronic calorimetry (phototubes, streamer tubes, etc.).
The GATE, CLR and BUSY signals are std. NIM levels (ECL on request). This unit implements an A24, D16 slave VME protocol.
