PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Operation Voltage Range VVD 2.9 5.5 V Reference Voltage (VREF) TA = -40°C to +85°C 2.5 Maximum Available Resolution CLEN=0 12 bits Full Scale Dynamic Range at Input (FSDRNOTE1) XPOS, YPOS, XNEG, YNEG, AUX0, AUX1, AUX2. VREF V AUX3 6.024 Absolute DC Conversion Error AUX3, measured with VVBAT=3.9V. -21 21 mV TSC Conversion Time ( Counts of internal clock cycles of the device) CLEN=0(for 12 bits resolution), Switch frequency 2MHz. 225 μs INLNOTE2 The standard deviation plus the 1st movement of the worst. INL and DNL are from DC sweep histogram analysis; Offset and Gain Error are from least square linear approximation, from data of input in 10% to 90% FSDR; Effective Numbers of Bits is the worst FWHMNOTE3 of reading a DC volume in same range. Test on channel 0 to channel 6 only, 12 bits conversion. -4 5 DNLNOTE2 -1 1 OffsetNOTE2 8 Gain ErrorNOTE2 1.5 Effective Numbers of BitsNOTE2 bit Input Impedance 11 MΩ Input capacitance 32 pF Input leakage Current 0.1 μA Touch Detection Trap Thresholds Voltage at the XPOS when pen touch trapped. 1 V Force Current At force driving voltage drop 5%. 17 mA Force Switch On-Impedance 4 Ω Conversion Operation Current 210 μA Shutdown Current 1 LSB Note: Guaranteed by design verification, characterization and production process control. NOTE1: DC Full Scale Dynamic Range at input. NOTE2: Guaranted by design verfication, characterization and production process control. NOTE3: Full Width of Half Magnititude.
