Introduction
The TVS-AMP series transimpedance amplifier is mainly used to convert weak photocurrent signals output by photomultiplier tubes (PMTs), PIN photodiodes, or other similar devices into voltage signals, while minimizing noise amplification. The amplifier has a large operating bandwidth and can achieve amplification from DC to 60 MHz (3 dB) with low output noise. The amplifier is equipped with an adjustable bias potentiometer, which can adjust the output bias voltage to maximize the dynamic range of the acquisition system or two-photon imaging controller. This amplifier uses SMA frequency connectors for input-output connections and can quickly connect to detectors and collectors. Very suitable for cross impedance amplification of PMT series such as Hamamatsu H7422, H10720, and H10721.
