Notes
8. The short circuit transient events on the VREF outputs must be limited to the voltage levels specified in the Maximum Ratings and slew
rates of less than 2.0 V/µs, otherwise damage to the part may occur. Refer to the paragraph Sensor Supplies (VREF1, VREF2) on page
17 and typical application circuit diagrams on Figure 8,and Figure 9 for recommended VREF output termination.
9. Guaranteed by design.
