Notes:

1.

All specifications are based on the test circuit shown on page 4

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.

Typical values are based on average measurements at room temperature

5.

This is the optimum impedance in order to achieve the performance shown
