DESCRIPTION
A versatile high grade a.cr pre-amplifier designed for
applications requiring ultra low noise such as infra-red
imaging and low noise wide band amplifiers e.g, micro-
phone, acoustic emission, transducer bridge amplifier.
The matching of open loop gain coupled with small phy-
sical size make the 2N459 series ideal for multichannel
amplification.

The input impedancemay be increasedat the expenseof noise by including R1 to vary the gain
