Note 1: Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation and by design.
Note 2: |∆VREF| is defined as the difference between the maximum and minimum values of VREF obtained over the full temperature range
Note 3: Refer to figure "Test circuit for Vka>Vref" page 4
