ESD SENSITIVITY

*Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings 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.

The ADSP-21020 features proprietary input protection circuitry to dissipate high energy discharges (Human Body Model). Per method 3015 of MIL-STD-883, the ADSP-21020 has been classified as a Class 3 device, with the ability to withstand up to 4000 V ESD.

Proper ESD precautions are strongly recommended to avoid functional damage or performance degradation. Charges readily accumulate on the human body and test equipment and discharge without detection. Unused devices must be stored in conductive foam or shunts, and the foam should be discharged to the destination socket before devices are removed. For further information on ESD precautions, refer to Analog Devices’ ESD Prevention Manual.
