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: R1IN ........................................................................... ±12V
R2IN .......................................................................... ±5.5V
CAP .................................. VANA + 0.3V to AGND2 – 0.3V
REF ......................................... Indefinite Short to AGND2,
Momentary Short to VANA
Ground Voltage Differences: DGND, AGND1, and AGND2 ............. ±0.3V
VANA ....................................................................................................... 7V
V
V
DIG to VANA ...................................................................................... +0.3V
DIG ........................................................................................................ 7V
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.
Digital Inputs ............................................................. –0.3V to VDIG + 0.3V
Maximum Junction Temperature ................................................... +165°C
Internal Power Dissipation ............................................................. 825mW
Lead Temperature (soldering, 10s) ............................................... +300°C
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.
