Charge preamplifying integrated circuit A101

low-noise

Designed for direct applications in the field of aerospace instrumentation, mass spectrometers, laboratory and research experiments, medical electronics, and electro-optical systems. Model A101 is a hybrid charge sensitive preamplifier, discriminator, and pulse shaper developed especially for instrumentation employing photomultiplier tubes, channel electron multipliers and other low capacitance charge producing detectors in the pulse counting mode. While this unit was specifically designed for satellite instrumentation, the following unique characteristics make it equally useful for space, laboratory and commercial applications: Features Small size (TO-8 package) allows mounting close to collector of multiplier. Power required is typically 15 mW. Single power supply voltage. Outputs interface directly with CMOS and TTL logic. Input threshold is externally adjustable. Output pulse width is variable with external trim capacitor. High reliability process. One year warranty.
