Note 7: **: Indicates post-reset initialization value (RESET = L).
Note 8: The formula for calculating resistance settings is as follows: This value is theory value. Actual current value contains error and so on in this value.
REXT [kΩ] = (1.9 × current rate 1 × current rate 2 × current rate 3 / output current [mA]) × (1 + (7 × current rate 4 / 105)) × 19.4
