This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han-
dling and installation procedures can cause damage.
Momentary Short to VANA
Ground Voltage Differences: DGND, AGND1, AGND2 ................. ±0.3V
VANA ....................................................................................................... 7V
VDIG to VANA ..................................................................................... +0.3V
VDIG ....................................................................................................... 7V
Digital Inputs ........................................................... –0.3V to +VDIG +0.3V
Maximum Junction Temperature ................................................... +165°C
Internal Power Dissipation............................................................. 825mW
Lead Temperature (soldering, 10s) ............................................... +300°C
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
