Notes

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

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

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

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

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

6. Measured with a 20 pF electrode, reference oscillator frequency of ~5 MHz (IREF = 5 Î¼A, REFCHRG = 4), PS = 128,

NSCN = 2; Iext = 16 (EXTCHRG = 15).

7. Typical value depends on the configuration used.

8. 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.
