GENERAL DESCRIPTION
bandgap voltage references offer precision performance
without premium price. These devices do not require thin-
film resistors, greatly lowering manufacturing complexity
and cost.
to 20mA operating current range make these devices at-
tractive for multimeter, data acquisition converter, and tele-
communication voltage references.
