Precision Adjustable Shunt Reference
AS2431
Electrical Characteristics
Electrical Characteristics are guaranteed over full junction temperature range (0 to 105¡C). Ambient temperature must be derated based
on power dissipation and package thermal characteristics. The conditions are: VKA = VREF and IK = 10 mA unless otherwise stated.
