Notes:
(1)Limits are 100 % production tested at 25 °C. Overtemperature limits are guaranteed through correlation and by design. (2)|ΔVREF| is defined as the difference between the maximum and minimum values of VREF obtained over the full temperature range. (3)Refer to Figure 4: "Test circuit for Vka = Vref". 4/16 DocID7961 Rev 6
