VIAMP
OEM solution combines VITUS SDD
with preamplifier in optional housing
The VIAMP preamplifier module is a specially designed OEM printed circuit board for operation with VITUS Silicon Drift Detectors (SDD) matching all types from 7mm² (H7) to 50mm² (H50) active area.
It offers a very low-noise, charge sensitive, ramped reset type electronic of positive polarity with onboard settings and filtering for all necessary SDD bias voltages.
An optional standard housing is functioning as heat sink. A customised version is available on request.
