3. CAPTRM=0, DELVOL=2, and fixed external capacitance of 20 pF.
4. CAPTRM=0, EXTCHRG=9, and fixed external capacitance of 20 pF.
5. The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current.
6. The programmable current source value is generated by multiplying the SCANC[EXTCHRG] value and the base current.
7. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16.
8. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16.
9. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16.
10. Sensitivity defines the minimum capacitance change when a single count from the TSI module changes, it is equal to (Cref
* Iext)/( Iref * PS * NSCN). Sensitivity depends on the configuration used. The typical value listed is based on the following
configuration: Iext = 5 μA, EXTCHRG = 4, PS = 128, NSCN = 2, Iref = 16 μA, REFCHRG = 15, Cref = 1.0 pF. The
minimum sensitivity describes the smallest possible capacitance that can be measured by a single count (this is the best
sensitivity but is described as a minimum because it’s the smallest number). The minimum sensitivity parameter is based
on the following configuration: Iext = 1 μA, EXTCHRG = 0, PS = 128, NSCN = 32, Iref = 32 μA, REFCHRG = 31, Cref= 0.5
pF
11. Time to do one complete measurement of the electrode. Sensitivity resolution of 0.0133 pF, PS = 0, NSCN = 0, 1
electrode, DELVOL = 2, EXTCHRG = 15.
12. CAPTRM=7, DELVOL=2, REFCHRG=0, EXTCHRG=4, PS=7, NSCN=0F, LPSCNITV=F, LPO is selected (1 kHz), and
fixed external capacitance of 20 pF. Data is captured with an average of 7 periods window.
