This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
AVDD to DVDD ...........................................................................–0.3V to 6V
AVDD to AGND .........................................................................–0.3V to 6V
DVDD to DGND .........................................................................–0.3V to 6V
AGND to DGND ................................................................................ ±0.3V
REFIN Voltage to AGND............................................ –0.3V to AVDD +0.3V
Digital Input Voltage to DGND .................................. –0.3V to DVDD +0.3V
Digital Output Voltage to DGND ............................... –0.3V to DVDD +0.3V
Lead Temperature (soldering, 10s) .............................................. +300°C
Internal Power Dissipation ............................................................. 500mW
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.
