ABSOLUTE MAXIMUM RATINGS
ELECTROSTATIC
DISCHARGE SENSITIVITY
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.
Analog Inputs to AGND: Any Channel Input ........ –0.3V to (+VD + 0.3V)
REFIN ............................. –0.3V to (+VD + 0.3V)
Digital Inputs to DGND .......................................... –0.3V to (+VD + 0.3V)
Ground Voltage Differences: AGND, DGND ................................... ±0.3V
+VD to AGND ......................... –0.3V to +6V
Power Dissipation .......................................................................... 325mW
Maximum Junction Temperature ................................................... +150°C
Operating Temperature Range ........................................–40°C to +85°C
Storage Temperature Range .........................................–65°C to +150°C
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.
