Product Description

The VATA64HDR16.2 is a 64-channel charge sensitive amplifier for SiPM read-out. Each channel features preamplifiers, “slow” shapers, sample/hold, multiplexed analogue readout and calibration facilities. Each channel has a “fast” shaper that gives a trigger signal and a timing unit to record the time difference between triggers in different channels.
Supported by the Galao ROIC Development Kit.
Keywords: Silicon photo multipliers, multi-pixel photon counters
