NOTES:
2. Tested at AV_DD = 20V.
3. Simulated and Determined via Design and NOT Directly Tested.
4. Simulated Maximum Current Draw when Programming EEPROM is 23mA, should be considered when designing Power Supply.
5. A Typical Current of 20µA is Calculated using the AVDD = 10V and RSET = 24.9kΩ. Reference “RSET Resistor” on page 5.
6. Simulated and Designed According to I²C Specifications.
7. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
