Notes: 1. Wafer level screening is performed at +25 °C and +85 °C only. However, performance is guaranteed over the full operating temperature range based on a

population of parts that were packaged and characterized at –55 °C and +125 °C.

2. Parameter not tested at wafer level due to high current limitations of test setup.
