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.
+VDD to GND ........................................................................ –0.3V to +6V
Digital Input Voltage to GND ................................. –0.3V to +VDD + 0.3V
Analog Input Voltage to GND ........................................... –0.3V to +6.0V
Operating Temperature Range ........................................–40°C to +85°C
Storage Temperature Range .........................................–65°C to +150°C
Junction Temperature (TJ max) .................................................... +150°C
TSSOP Package
Power Dissipation .................................................... (TJ max – TA)/θJA
θJA Thermal Impedance ...................................................... +240°C/W
Lead Temperature, Soldering
ESD damage can range from subtle performance degradation
tocompletedevicefailure. Precisionintegratedcircuitsmaybe
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
Vapor Phase (60s) ............................................................ +215°C
Infrared (15s) ..................................................................... +220°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.
