GENERAL DESCRIPTION
The TC9491 (1.220V output) bipolar, two-terminal,
bandgap voltage references offer precision performance
without premium price. These devices do not require thin-
film resistors, greatly lowering manufacturing complexity
and cost.
A 50ppm/
°
C output temperature coefficient and a 15
μ
A
to 20mA operating current range make these devices at-
tractive for multimeter, data acquisition converter, and tele-
communication voltage references.
