! Denotes Special Characteristics: These characteristics have been identified as important to the
customer.
Notes:
1.
2.
Cross axis sensitivity is dominated by the placement accuracy of the component during PCB
assembly and in the application.
Bandwidth for internal low pass filter only. Lower frequencies are user definable with external
capacitors. (See Application Design Equations)
