6 / 13 page 6 FN6678.2 September 9, 2015 Slow Mode Timing 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)31 – V(RW)0]/31. V(RW)31 and V(RW)0 are voltage on RW pin for the DCP register set to 1F 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 31; i is the DCP register setting. 10. INL = [V(RW)i – i • LSB – V(RW)]/LSB for i = 1 to 31 11. for i = 5 to 31 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 = |RW31 – RW0|/31. MI is a minimum increment. RW31 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 = RW31/MI, when measuring between RW and RH. 14. RDNL = (RWi – RWi-1)/MI, for i = 1 to 31. 15. RINL = [RWi – (MI • i) – RW0]/MI, for i = 1 to 31. 16. for i = 5 to 31, 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. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested. TCV Max V RW i Min V RW i – Max V RW i Min V RW i + 2 ---------------------------------------------------------------------------------------------- 106 +165°C --------------------- = TCR Max Ri Min Ri – Max Ri Min Ri + 2 ---------------------------------------------------------------- 10 6 +165°C --------------------- = tGAP tDB MI* VW PU *MI in the AC timing diagram refers to the minimum incremental change in the wiper voltage.
