IRDM982-025MB/-035MB Electrical Characteristics

Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage

parameters are absolute voltages referenced to VSS unless otherwise stated in the table. The thermal resistance and

power dissipation ratings are measured under board mounted and still air conditions.

Ta=25C, unless otherwise stated.
