(Continued) SYMBOL PARAMETER TEST CONDITIONS MIN (Note 18) TYP (Note 5) MAX (Note 18) UNIT DC Electrical Specifications Over recommended operating conditions unless otherwise specified. SYMBOL PARAMETER TEST CONDITIONS MIN (Note 18) TYP (Note 5) MAX (Note 18) UNIT ICC VCC Active Current VCC = 5.5V, perform wiper move operation 150 µA ICC VCC Current During Store Operation VCC = 5.5V, perform non-volatile store operation 2mA ISB Standby Current 0.6 3 µA ILkg PU, PD Input Leakage Current VIN = VSS to VCC -2 +2 µA VIH PU, PD Input HIGH Voltage VCC x 0.7 V VIL PU, PD input LOW Voltage VCC x 0.1 V CIN (Note 17) PU, PD Input Capacitance VCC = 3.3V, TA = +25°C, f = 1MHz 10 pF Rpull_up (Note 17) Pull-Up Resistor for PU and PD 1M Ω AC Electrical Specifications Over recommended operating conditions unless otherwise specified. SYMBOL PARAMETER MIN (Note 18) TYP (Note 5) MAX (Note 18) UNIT tGAP Time Between Two Separate Push Button Events 2 ms tDB Debounce Time 15 28 ms tS SLOW Wiper Change on a Slow Mode 100 250 390 ms tS FAST Wiper Change on a Fast Mode 25 50 78 ms tstdn (Note 17) Time to Enter Shutdown Mode (keep PU and PD LOW) 2 s tPU Power-Up to Wiper Stable 500 µs tR VCC VCC Power-Up Rate 0.2 50 V/ms NOTES: 5. Typical values are for TA = +25°C and 3.3V supply voltage. 6. LSB: [V(RW)15 – V(RW)0]/15. V(RW)31 and V(RW)0 are voltage on RW pin for the DCP register set to 0F hex and 00 hex respectively. LSB is the incremental voltage when changing from one tap to an adjacent tap. 7. ZS error = V(RW)0/LSB. 8. FS error = [V(RW)31 – VCC]/LSB. 9. DNL = [V(RW)i – V(RW)i-1]/LSB -1, for i = 1 to 15; i is the DCP register setting. 10. INL = [V(RW)i – i • LSB – V(RW)]/LSB for i = 1 to 15 11. for i = 5 to 15 decimal, T = -40°C to +125°C. Max( ) is the maximum value of the wiper voltage and Min ( ) is the minimum value of the wiper voltage over the temperature range. 12. MI = |RW 15 – RW0|/15. MI is a minimum increment. RW15 and RW0 are the measured resistances for the DCP register set to 1F hex and 00 hex respectively. 13. Roffset = RW0/MI, when measuring between RW and RL. Roffset = RW15/MI, when measuring between RW and RH. 14. RDNL = (RWi – RWi-1)/MI, for i = 1 to 15. 15. RINL = [RWi – (MI • i) – RW0]/MI, for i = 1 to 15. 16. for i = 5 to 15, T = -40°C to +125°C. Max( ) is the maximum value of the resistance and Min ( ) is the minimum value of the resistance over the temperature range. 17. Limits should be considered typical and are not production tested. 18. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.
