*Stresses greater than those listed under Absolute Maximum Ratings may cause
permanent damage to the device. T his is a stress rating only; functional operation
of the device at these or any other conditions above those indicated in the
operational section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

AMB = T CASE – (PD × θCA)
T CASE = Case T emperature in °C
PD = Power Dissipation in W
θCA = T hermal Resistance (Case-to-Ambient)

CAUTIO N
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 AD1845 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!
