Defined by design, not tested.

Note: This signal has an individual error ±5 % in each of the three currents levels, at trimming temperature of 130 °C. Additional

an individual error ± 10 % in each of the three current levels over temperature and aging. So the maximum error is of

± 15 % in each of the three current levels. The offset and the gain errors may be different in each current level.

The adjustment is done at 130 °C and compensates the error between 0.3 * Imax to 0.6 * Imax.
