簡介
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.
