4 / 18 page Absolute Maximum Ratings (Note 2) Supply Voltage −0.3 V to 6.0 V Voltage at Any Pin −0.3 V to (V DD + 0.5 V) Input Current at Any Pin (Note 3) ±5mA Storage Temperature −65˚C to +150˚C ESD Susceptibility (Note 5) Human Body Model 2000 V Machine Model 200 V Soldering process must comply with National Semiconductor’s Reflow Temperature Profile specifications. Refer to www.national.com/packaging. (Note 4) Operating Ratings (Note 2) Specified Temperature Range T MIN ≤T A ≤T MAX -40˚C ≤T A ≤+150˚C Supply Voltage Range (V DD) +2.7V to +5.5V Temperature-to-Digital Converter Characteristics Unless otherwise noted, these specifications apply for V DD = 2.7V to 5.5V. Boldface limits apply for TA =TJ =TMIN to TMAX; all other limits T A =TJ = +25˚C, unless otherwise noted. TA is the ambient temperature. TJ is the junction temperature. Parameter Conditions Typical Limits Units (Note 6) (Note 7) (Limit) Accuracy (Note 8) V DD = 2.7V to V DD = 4.5V T A = −10˚C to 80˚C ±1.0 ˚C (max) T A = −25˚C to 115˚C ±1.5 ˚C (max) T A = −40˚C to 150˚C ±2.0 ˚C (max) V DD > 4.5V to V DD = 5.5V T A = −10˚C to 80˚C ±1.5 ˚C (max) T A = −25˚C to 115˚C ±2.0 ˚C (max) T A = −40˚C to 150˚C ±2.5 ˚C (max) Resolution RES1 Bit = 0, RES0 Bit = 0 11 Bits 0.25 ˚C/LSB RES1 Bit = 0, RES0 Bit = 1 12 Bits 0.125 ˚C/LSB RES1 Bit = 1, RES0 Bit = 0 13 Bits 0.0625 ˚C/LSB RES1 Bit = 1, RES0 Bit = 1 14 Bits 0.03125 ˚C/LSB Temperature Conversion Time (Note 9) RES1 Bit = 0, RES0 Bit = 0 10.1 14 ms (max) RES1 Bit = 0, RES0 Bit = 1 20.2 28 ms (max) RES1 Bit = 1, RES0 Bit = 0 40.4 56 ms (max) RES1 Bit = 1, RES0 Bit = 1 80.8 112 ms (max) Quiescent Current Continuous Conversion Mode, SMBus inactive 320 495 µA (max) Shutdown, bus-idle timers on 120 175 µA (max) Shutdown, bus-idle timers off 1.9 8 µA (max) Power-On Reset Threshold Measured on V DD input, falling edge 0.9 V (min) www.national.com 4 |
