Fast

Transimpedance preamplifier

FIP is a series of high speed, transimpedance, AC coupled preamplifiers, intended to operate with biased TE cooled VIGO detectors. Fast preamplifier enables precise I-V conversion, detector biasing up to 800 mV and simultaneously maintains compact size and keeps current noise low. FIP is equipped with a fan and does not require additional heat dissipation. It is suitable for applications requiring wide frequency bandwidth. Additional DC output is available as an option.

Types of VIGO detectors that can be integrated with FIP preamplifier

  • Photovoltaic biased: PV-2TE, PV-3TE, PV-4TE
  • Photovoltaic biased, optically immersed: PVI-2TE, PVI-3TE, PVI-4TE
