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.

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.
