The Standford Research SR445 Fast Preamp contains four wide bandwidth, DC coupled amplifiers designed to be used independently or cascaded to provide gains of 5, 25, and 125. The fast rise time, low noise, and DC accuracy of the SR445 make it the ideal instument for amplifying outputs of fast photomultiplier tubes and photodiodes.

The SR445 is useful for amplifying small signals to levels that allow processing by other instruments such as the SR430 or the SR400. The four channels may be used independently or cascaded.
