AS432
1.24V Precision Adjustable Shunt Reference/Amplifier
Electrical Characteristics
Electrical characteristics are guaranteed over the full junction temperature range (0D105C). Ambient temperature must be derated
based upon power dissipation and package thermal characteristics. Unless otherwise stated, test conditions are: V
KA
= V
REF
and
I
K
= 10 mA.
