(1) All hot and cold limits are specified by correlating the electrical characteristics to process and temperature variations and applying
statistical process control.
(2) The junction temperature (TJ in °C) is calculated from the ambient temperature (TA in °C) and power dissipation (PD in Watts) as follows:
TJ = TA + (PD × RθJA) where RθJA (in °C/W) is the package thermal impedance provided in the Thermal Information section.
(3) RSET is based on 1% E96 standard resistor values.
(4) "+1" LSB implies a positive step in CODE. LSB is in reference to LSB_4.
