(1)

Test levels: (A) 100% tested at +25°C. Over temperature limits set by characterization and simulation. (B) Limits set by characterization

and simulation only. (C) Typical value only for information.

(2)

3.3-V supply filter specifications are ensured by 100% testing at 5-V supply along with design and characterization.
