XGCSA - The smallest Charge Sensitive Amplifiers for radiation detectors
The XGCSA are the new XGLAB’s family of Charge Sensitive Amplifiers designed to read different types of solid-state photodetectors with selectable polarity. They are available in two different package options, QFN12 (Q) and PSOIC16 (S) and cover three different detector capacitance ranges.
Main characteristics
- Polarity: electrons or holes collection, selectable
- Supply voltages: ±2.5 V and -6 V
- Detector capacitance: see Table 1
- Feedback capacitance: 50 fF / 150 fF / 500 fF
- ENC: 25e- @ 1µs
- Reset: continuous or pulsed
Applications
- X and Gamma rays spectroscopy
- Particle physics experiments
- PIN diodes
- CdTe or CZT detectors
- High purity germanium detectors
- Strip detectors
