NOTES:
6. CTL signal only needs to be greater than 4.9V to program EEPROM.
7. Tested at AV_DD = 20V.
8. The Counter value is set to mid-scale ±4 LSB’s in the Production.
9. Simulated and Determined via Design and NOT Directly Tested.
10. Simulated Maximum Current Draw when Programming EEPROM is 23mA; should be considered when designing Power Supply.
11. A Typical Current of 20µA is Calculated using AV_DD = 10V and R_SET = 24.9kΩ. Reference “RSET Resistor” on page 6.
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 6 with Setting = 128.
13. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
