Analog Input Voltage ................................. AGND – 0.3V to AV_DD + 0.3V
Reference Input Voltage ........................... AGND – 0.3V to AV_DD + 0.3V
Digital Input Voltage .................................. BGND – 0.3V to BV_DD + 0.3V
Ground Voltage Differences, AGND to BGND ................................ ±0.3V
Voltage Differences, BV_DD to AGND ..................................... –0.3V to 7V
Input Current to Any Pin Except Supply ......................... –20mA to 20mA
Power Dissipation ....................................... See Dissipation Rating Table
Operating Virtual Junction Temperature Range, T_J ...... –40°C to +150°C
Operating Free-Air Temperature Range, T_A .................. –40°C to +125°C
Storage Temperature Range, T_STG ................................ –65°C to +150°C
NOTE: (1) Stresses beyond those listed under Absolute Maximum Ratings may
cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those
indicated under Recommended Operating Conditions is not implied. Exposure
to absolute-maximum-rated conditions of extended periods may affect device
reliability.
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.
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.
