Low Noise Amplifier

Low Noise Amplifier 型號:EL-LNA-2
  • Gain x10 and x100
  • Differential input stage
  • Input noise 4.5 nV / (Hz) 1/2
  • Input impedance 1 MOhm
  • Max. Output Voltage Swing
    • ± 2.5 V @ no load
    • ± 1.25 V @ 50 Ohm
  • Bandwidth 20 MHz (G=10), 15 MHz (G=100)
  • The amplifier EL-LNA-2 is designed as a differential low noise amplifier with two gain stages of x10 and x100 with a full bandwidth of 20 MHz (at G=10)

    While the EL-LNA-2 is matched to connect to an Elsys high-precision Transient Recorder it is also suitable for any 3rd party data acquisition system.
