ABSOLUTE MAXIMUM RATINGS(1)
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
Analog Inputs: VIN ............................................................................. ±25V
REF.................................................. +VANA + 0.3V to AGND2 – 0.3V
CAP ..................Indifinite Short to AGND2 Momentary Short to VANA
Ground Voltage Differences: DGND, AGND1, AGND2 ................... ±0.3V
VANA ....................................................................................................... 7V

DIG to VANA ...................................................................................... +0.3V
DIG ........................................................................................................ 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 degradation
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.
NOTE: (1) Stresses above those listed under Absolute Maximum Ratings may
cause permanent damage to the device. Exposure to absolute maximum
conditions for extended periods may affect device reliability.
