Notes:
1.
All specifications are based on the test circuit shown on page 5
2.
In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
3.
Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
4.
Excluding losses due to PCB
Subject to change or obsolescence without notice
