Charge preamplifier A250CF

low-noise

The Amptek A250CF CoolFET® Charge Sensitive Preamplifier is the lowest noise, general purpose, preamplifier available. It is designed to give the ultimate performance when used with either low or high detector capacitance detectors and is a direct replacement for other higher noise charge sensitive preamplifiers. The A250CF CoolFET® technology uses a thermoelectric (Peltier) cooler to keep the input FET(s) at -50 °C. Cooling is totally transparent to the user. Hence, the A250CF CoolFET® operates like a room temperature preamplifier. Based on the successful A250 charge sensitive preamplifier designed for high performance satellite instrumentation, the A250CF CoolFET® re-defines the new state-of-the-art. Power to the A250CF CoolFET® is provided by an external stable power supply (included). Detector bias can be applied via an SHV connector. Input, E-Output, T-Output and Test are provided via BNC connectors.
