Benefits
- Digital measuring principle in CMOS technology
- Up to 8 capacitances in grounded mode
- Up to 4 capacitances in floating mode (potential- free and with zero bias voltage)
- Compensation of internal (grounded) and external parasitic capacities (floating)
- High resolution: up to 6 aF at 5 Hz and 10 pF base capacitance, or 17 bit resolution at 5 Hz with 100 pF base capacitance and 10 pF excitation
