Model AM8000 Fast Timing amplifier modules

DC coupled, low noise, high bandwidth

Fast Pulse / Timing amplifier modules for plugging into a TA8008

FEATURES 

  • 9 different amplifier modules available
  • DC coupled
  • Small signal bandwidths of more than 2 GHz available, model dependent
  • Voltage gains from 14dB (x5) to 46dB (x200)
  • Non-inverting closed loop OP-Amp design
  • Low and very low noise models
  • High output drive
  • Bandwidth limited (BWL) options available for further improved noise performance
  • Offset adjustment

APPLICATIONS 

  • Pre-amps for ultra fast detectors (MCP, PMT, ...)
  • Oscilloscope and transient recorder pre-amps
  • Photon-/Ion- counting
  • Wideband signal processing

 

DESCRIPTION
The pool of available AM8000 fast timing amplifiers consists of 3 basic families:
- AM81xx  low noise, high bandwidth
- AM82xx  high bandwidth, high gain
- AM83xx  very low loise

Each AM83xx model is also available with a bandwidth limited (BWL) option which further reduces the noise floor.

A unique feature for such high speed amplifiers is the DC coupling. DC coupling avoids count rate effects due to non DC balanced pulse trains and the corresponding charging of coupling capacitors.
