5182 - Signal Recovery Current Amplifiers


Get Quote

  • Model: 5182
  • Manufactured by: Signal Recovery
  • Bandwidth: 1.00MHz
  • Gain [V/A]: 10^8
  • Input Noise: 15 fA/Hz^1/2
  • Extra Specifications: Current Sensitive Preamplifier

The model 5182 is a current-to-voltage preamplifier of low noise and low input impedance designed to amplify the extremely low  low currents encountered in such areas as photometry and semiconductor research. It has four standard conversion factors but in addition includes a special low-noise mode on the highest gain position for even better low current measurement capability. The unit features two outputs, allowing both the AC and DC components of the input signal to be independently monitored, so that, for example, in a PMT application the bias current can be measured separately from the signal current.

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 5182 is ideally suited to amplifying signals from current sources such as electron multipliers, ion collectors, photomultipliers and photodiodes.
