Long-Term Drift
Long-termdriftcannotbeextrapolatedfromaccelerated
hightemperaturetesting.Thiserroneoustechniquegives
drift numbers that are wildly optimistic. The only way
long-term drift can be determined is to measure it over
the time interval of interest. The LT1460S3 long-term
drift data was taken on over 100 parts that were soldered
into PC boards similar to a “real world” application. The
boards were then placed into a constant temperature oven
with TA = 30°C, their outputs were scanned regularly and
measured with an 8.5 digit DVM. Figure 16 shows typical
long-term drift of the LT1460S3s.
Hysteresis
HysteresisdatashowninFigure17andFigure18represents
the worst-case data taken on parts from 0°C to 70°C and
from –40°C to 85°C. The device is capable of dissipating
relativelyhighpower,i.e.,fortheLT1460S3-2.5,PD=17.5V
20mA = 350mW. The thermal resistance of the SOT-23
package is 325°C/W and this dissipation causes a 114°C
internal rise producing a junction temperature of TJ=25°C
+ 114°C = 139°C. This elevated temperature will cause
the output to shift due to thermal hysteresis. For highest
performance in precision applications, do not let the
LT1460S3’s junction temperature exceed 85°C.
