NOTES
1Absolute maximum ratings are limiting values to be applied individually and
beyond which the serviceability of the circuit may be impaired. Functional
operability is not necessarily implied. Exposure to absolute maximum rating
conditions for an extended period of time may affect device reliability.
2Typical thermal impedances (parts soldered to board):
N Package (PDIP): JA = 42°C/W; JC = 10°C/W.
R Package (SOIC): JA = 47°C/W; JC = 10°C/W.

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
AD9040A 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.
