NOTES:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
7. I_DD current may increase to 2mA for 45ms or less during each EEPROM programming operation.
8. I_AVDD current may increase to 1mA for 30ms or less during each EEPROM programming operation.
9. Simulated and Determined via Design and NOT Directly Tested.
10. Simulated and Designed According to I²C Specifications.
11. A typical Current of 20μA is Calculated using AV_DD = 10V and R_SET = 24.9kΩ. Reference “R_SET Resistor” in Figure 2.
12. Minimum value of R_SET resistor guaranteed when: AV_DD = 15V, V_DD = 3.0V and when voltage on the VOUT pin is greater than 2.5V. Reference
Equation 2 on page 5 with Setting = 128.
