A1425
Fast Charge Sensitive Preamplifier
Features
- Fast, inverting preamplifier
- Sensitivity of 3.6 mV/fC
- ENC of 0.16 fC (1000 e)
- Output impedance of 50 Ohm
- Output range 0 to 1 V
- Up to 1 kV (positive or negative) detector bias voltage
Overview
The A1425 is a fast and low noise preamplifier with AC coupled input. The fast rise time makes it suited for amplifying the signals from detectors as fast silicon sensors and diamond detectors.
It has been designed for spectroscopy applications, and can be combined with sub-nanosecond measurements of particle time-of flight. It is optimized for high-speed single MIP particle detection with diamond detectors, where the signal integrated change is extremely small. It integrates a high voltage input for detector bias up to 1 kV.
