Weeroc is a spin-off company from Omega laboratory (IN2P3/ CNRS French governmental agency for fundamental research in astrophysics, particle physics and nuclear physics) and today offers a full range of products to read out almost

any kind of detector. In particular, it provides off-the-shelf programmable analog and mixed front-end ASICs for photon and particle detectors readout, together with Testboards specifically designed for each ASIC.

Weeroc main customers are the major actors in the fields of:

• Medical imaging
• Homeland security
• Nuclear protection
• Scientific instrumentation
• Space (launchers and satellites)

In order to widen the adoption of Weeroc ASICs, CAEN developed specifically the DT5550W a system designed
to extensively test the ASICs. The DT5550W has a user programmable FPGA allowing the user to characterize the performance of one or multiple chips and build a complete DAQ system.

Moreover CAEN offers a solution based on CITIROC ASIC, for SiPM arrays readout.
