Dimensions

1. The TSI module is functional with capacitance values outside this range. However, optimal performance is not guaranteed.

2. Fixed external capacitance of 20 pF.

3. REFCHRG = 2, EXTCHRG=0.

4. REFCHRG = 0, EXTCHRG = 10.

5. VDD = 3.0 V.

6. The programmable current source value is generated by multiplying the SCANC[REFCHRG] value and the base current.

7. The programmable current source value is generated by multiplying the SCANC[EXTCHRG] value and the base current.

8. Measured with a 5 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 8; Iext = 16.

9. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 128, NSCN = 2; Iext = 16.

10. Measured with a 20 pF electrode, reference oscillator frequency of 10 MHz, PS = 16, NSCN = 3; Iext = 16.

11. Sensitivity defines the minimum capacitance change when a single count from the TSI module changes. Sensitivity

depends on the configuration used. The documented values are provided as examples calculated for a specific

configuration of operating conditions using the following equation: (Cref * Iext)/( Iref * PS * NSCN)

The typical value is calculated with the following configuration:

Iext = 6 μA (EXTCHRG = 2), PS = 128, NSCN = 2, Iref = 16 μA (REFCHRG = 7), Cref = 1.0 pF

The minimum value is calculated with the following configuration:

Iext = 2 μA (EXTCHRG = 0), PS = 128, NSCN = 32, Iref = 32 μA (REFCHRG = 15), Cref = 0.5 pF

The highest possible sensitivity is the minimum value because it represents the smallest possible capacitance that can be

measured by a single count.

12. Time to do one complete measurement of the electrode. Sensitivity resolution of 0.0133 pF, PS = 0, NSCN = 0, 1

electrode, EXTCHRG = 7.

13. 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.
