Note 1: **: Indicates post-reset initialization value (RESET= L).
Note 2: 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] = { (1.8 × cur rent rate 1 × current rat e 2 × current rate 3) × (current rate 4 × 34.5) } ÷ output current [mA]
