Electrical Characteristics

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to

any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.

Note 2: The ADPL21210 are guaranteed to meet performance specifications from 0°C to 85°C, junction temperature. Specifications

over the –40°C to 85°C operating junction temperature range are assured by design, characterization and correlation with

statistical process controls.
