Electrical performance characteristics - Continued. 1/ Testing and other quality control techniques are used to the extent deemed necessary to assure product per
36、formance over the specified temperature range. Product may not necessarily be tested across the full temperature range and all parameters may not necessarily be tested. In the absence of specific parametric testing, product performance is assured by characterization and/or design. 2/ VDD= 3 V to 5.5
37、 V, VSS=0; VDD= 2.5 V, VSS= -2.5 V, VA= VDD, VB= VSS, -40C TA 125C (unless otherwise noted). The part can be operated at 2.7 V single supply, except from 0C to -40C, where a minimum of 3 V is needed. 3/ Typicals (TYP) represent average readings at 25C and VDD= 5V. 4/ Resistor position nonlinearity e
38、rror (R-INL) is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper positions. R-DNL measures the relative step change from ideal between successive tap positions. IW 50 A for VDD= 2.7 V and IW 400 A for VDD= 5 V. 5/ INL and DNL are measured at
39、VW with the RDAC configured as a potentiometer divider similar to a voltage output DAC. VA= VDDand VB= VSS. DNL specification limits of 1 LSB maximum guaranteed monotonic operating conditions. 6/ Resistor terminal A, Resistor terminal B, and resistor terminal W has no limitations on polarity with re
40、spect to each other. Dual supply operation enables ground-referenced bipolar signal adjustment. 7/ Guaranteed by design and not subject to production test. 8/ Common mode leakage current is a measure of the dc leakage from any terminal A, terminal B, or terminal W to a common mode bias level of VDD/
41、2. 9/ EEMEM response mode current is not continuous. Current is consumed while EEMEM locations are read and transferred to the RDAC register. To minimize power dissipation, on a NOP, instruction 0 (0x0) should be issued immediately after instruction 1 (0x1). 10/ PDISSis calculated from (IDDx VDD) +
42、(ISSx VSS). 11/ All dynamic characteristics use VDD= +2.5 V and VSS= -2.5 V. 12/ Guaranteed by design and not subject to production test. See the timing diagrams section for the location of measured values. All input control voltages are specified with tR= tF= 2.5 ns (10% to 90% of 3 V) and timed fr
43、om a voltage level 0f 1.5 V. Switching characteristics are measured using both VDD= 3 V and VDD= 5 V. 13/ Propagation delay depends on the value of VDD, RPULL-UP, and CL. 14/ Valid for commands that do not activate the RDY pin. 15/ RDY pin low only for Instruction 2, Instruction 3, Instruction 8, In
44、struction 9, Instruction 10, and the PRhardware pulse; CMD_8 20 s; CMD_9, CMD_10 7 s; CMD_2, CMD_3 15 ms; PRhardware pulse 30 s. 16/ Store EEMEM time depends on the temperature and EEMEJM writes cycles. Higher timing is expected at a lower temperature and higher write cycles. 17/ Not shown in FIGURE
45、 5 and FIGURE 6. 18/ Endurance is qualified to 100,000 cycles per JEDEC standard 22, method A117 and measured at -40C, +25C, and +125C. 19/ Retention life time equivalent at junction temperature (TJ) = 85C per JEDEC standard 22, method A117.
