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.
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.
Supply Voltage, V+ to V–.................................................................... 36V
Signal Input Terminals, Voltage ........................................................ ±80V
Current ....................................................... ±1mA
Output Short Circuit (to ground).............................................. Continuous
Operating Temperature ..................................................–55°C to +125°C
Storage Temperature .....................................................–55°C to +150°C
Junction Temperature.................................................................... +150°C
Lead Temperature (soldering, 10s)............................................... +240°C
NOTE: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade
device reliability.

NOTE: (1) Models with a slash (/) are available only in Tape and Reel in the quantities indicated (e.g., /2K5 indicates 2500 devices per reel). Ordering 2500 pieces
of “INA145UA/2K5” will get a single 2500-piece Tape and Reel.
