1.24V Precision Adjustable Shunt Reference/Amplifier
AS432
Electrical Characteristics
Electrical characteristics are guaranteed over the full junction temperature range (0Ð105¡C). Ambient temperature must be derated
based upon power dissipation and package thermal characteristics. Unless otherwise stated, test conditions are: VKA = VREF and
IK = 10 mA.

*Temperature deviation is defined as the maximum deviation of the reference over the given temperature range and does not imply
an incremental deviation at any given temperature.
