Model 5183
Nanovolt Preamplifier
General
The model 5183 is a high input impedance, AC coupled voltage preamplifier
which features a very low noise input stage. It has a frequency response
from 0.5 Hz to 1 MHz and a fixed gain of x1000 (60 dB) and
incorporates a special pseudo-differential input stage that can be floated
to give the ground loop immunity normally associated with differential
inputs but without the associated noise penalty. It can be powered from
its own internally housed (alkaline) batteries, an external low voltage
supply (±15 V or ±18 V) or from the model PS0108 remote line power
supply (optional extra). This preamplifier can also be powered from most
of our range of lock-in amplifiers and from the model 7310 noise rejecting
voltmeter
The model 5183 is ideally suited for amplifying signals from high
impedance cryogenic sources, capacitance transducers and IR detectors such
as Ge, Si, PbS, PbSe and InGaAs.
