NOTES
1_{Stresses above those listed under “Absolute Maximum Ratings” may cause}
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2_{Thermal Characteristics: 8-Pin SOIC Package: θJA = 160°C/W, θJC = 42°C/W;}
8-Pin Plastic Package: θ_JA = 90°C/W; 8-Pin Cerdip Package: θ_JC = 22°C/W, θ_JA =
110°C/W; 8-Pin Metal Can Package: θ_JC = 65°C/W, θ_JA = 150°C/W.
3_{For supply voltages less than ± 18 V, the absolute maximum input voltage is equal}
to the supply voltage.

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 AD548 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!
