Charge preamplifying integrated circuit A111

low-noise

Designed for direct applications in the field of aerospace and portable instrumentation, mass spectrometers, particle detection, imaging, laboratory and research experiments, medical electronics and electro-optical systems. Model A111 is a hybrid charge sensitive preamplifier, discriminator, and pulse shaper developed especially for instrumentation employing microchannel plates (MCP), channel electron multipliers (CEM), photomultipliers, proportional counters and other low capacitance charge producing detectors in the pulse counting mode. While this unit was developed for NASA's deep space probes, the following unique characteristics make it equally useful for space, laboratory and commercial applications: Features Small size (TO-8 package) allows mounting close to detector. (6-pin SIP available as model A111F) Power required is typically 6 milliwatts. Single power supply voltage. Output interfaces directly with CMOS and TTL logic. Input threshold is externally adjustable. Analog monitor point. High reliability process. One year warranty.
