Current Amplifiers
Variable-Gain Ultra-Low-Noise DDPCA-300

  • 0.4 fA peak-peak noise
  • Very high dynamic range: Sub-fA to 1 mA (>240 dB)
  • Transimpedance (Gain) switchable from 1 x 104 to 1 x 1013 V/A
  • Bandwidth up to 450 Hz, Rise Time down to 0.8 ms - Independent of Source Capacitance (up to 10nF)
  • Adjustable Bias-Voltage on Input Relative to Ground
  • Compact Housing for use close to the signal source
  • Protection against +2kV transients
  • Local and Remote Control
  • East to use:
    Convert your standard digital voltmeter or DAQ Board to a high-end Digital Sub-Femotamperemeter

Applications:

  • Photodetector amplifier
  • I/V characterization of small MOS structures
  • DC measurements of ultra low currents
  • Ionization detectors, mass spectrometry, quantum and biotech experiments
  • Spectroscopy
  • High resistance measurements
The LUCI-10 amplifier interface allows remote control of FEMTO amplifiers and photoreceivers with a remote control capability from a standard Windows PC with USB port.
