Supplier: Signal Recovery


  • Very low-noise
  • Gains 60dB
  • Battery or mains operation

It has a frequency response from 0.5 Hz to 1 MHz and a fixed gain of x1000 (60 dB) and incorporates a special pseudo-differential input stage that can be floated to give the ground loop immunity normally associated with true differential inputs but without the associated noise penalty.


  • Gains 60dB
  • Input / output impedance 5MΩ / 450Ω
  • Noise 800pV / √Hz
  • Frequencies from 0.5Hz to 1Mhz

Product applications

  • Preamplification for Cryogenic Detector HgCdTe, InSb, InAs
  • IR Pre-amplification
