Transimpedance preamplifier

PIP is a series of programmable “smart” preamplifiers. Due to the modern internal configuration, it offers extreme flexibility combined with superior signal parameters and high reliability. Built-in voltage monitor allows to check and optimize the working conditions (supply voltages, detector bias voltage, first and last stage output voltage offset etc.).

Types of VIGO detectors that can be integrated with PIP preamplifier

  • Photoconductive: PC-2TE, PC-3TE, PC-4TE
  • Photoconductive optically immersed: PCI-2TE, PCI-3TE, PCI-4TE
  • Photovoltaic: PV-2TE, PVA-2TE, PV-3TE, PV-4TE
  • Photovoltaic optically immersed: PVI-2TE, PVIA-2TE, PVI-3TE, PVI-4TE
  • Photovoltaic multiple junction: PVM-2TE
  • Photovoltaic multiple junction optically immersed: PVMI-2TE, PVMI-3TE, PVMI-4TE
