2 / 25 page www.ti.com ABSOLUTE MAXIMUM RATINGS (1) ELECTRICAL CHARACTERISTICS ADS8505 SLAS180B – SEPTEMBER 2005 – REVISED JUNE 2007 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal.
