(Note 24) Full Range: TA=-40°C to +85°C
(Note 25) Consider the power dissipation of the IC under high temperature environment when selecting the output current value.
There may be a case where the output current value is reduced due to the rise in IC temperature caused by the heat generated inside the IC.
(Note 26) Output load resistance connects to a half of VDD.
