*Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any other conditions above those listed in the operational sections

of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect

device reliability.

*␪JA is measured using a 4-layer PCB with the exposed paddle

soldered to the board.

*This is a lead free product.

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 AD9948 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.
