Fast, transimpedance amplifierFIP series

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