CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP270 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
WARNING!

qJA is specified for worst-case mounting conditions, i.e., qJA is specified
for device in socket for Cerdip and P-DIP packages;
qJA is specified for
device soldered to printed circuit board for SOL package.
NOTES:
1Absolute maximum ratings apply to both DICE and packaged pans,
unless otherwise noted.
2The OP270’s inputs are protected by back-to-back diodes.
Current limiting resistors are not used in order to achieve low noise
performance. lf differential voltage exceeds +10 V, the input current
should be limited to
± 25 mA.
