1The analog input voltage is equal to ±7 V or the analog supply voltage, whichever

is less.

2θJA is specified for the worst case conditions, i.e., θJA is specified for device in socket

for P-DIP and θJA is specified for device soldered in circuit board for SOIC and

TSSOP packages.

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 AD8598 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.
