GENERAL DESCRIPTION
The AMS9491 is a two-terminal micropower band-gap voltage reference diode.
It feature a very low dynamic impedance and good temperature coefficient, operating over a 10µA to 20mA current range.
On-chip trimming is used to provide tight voltage tolerance.
Since the AMS9491 is a band-gap reference, u...
