2.1 Product description
eONE (Miniaturized One-Channel Amplifier) is a new current measurement sys-
tem entirely contained in a USB stick, thanks to a custom-made microchip for
low-noise current signal acquisitions.
2.2 Key features
• Two input current ranges: ±200 pA and ±20 nA;
• Eight selectable sampling rates: 1.25 kHz, 5 kHz, 10 kHz, 20 kHz, 40 kHz,
50 kHz, 100 kHz and 200 kHz;
• Very low noise: ≈100 fA rms at 1 kHz, ≈380 fA rms at 10 kHz & ≈3,2 pA
rms at 100 kHz (open input);
• Software controlled voltage stimulus with 1mV resolution;
