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 15µA

to 20mA operating current range make these devices at-

tractive for multimeter, data acquisition converter, and tele-

communication voltage references.

APPLICATIONS

ADC and DAC Reference

Current Source Generation

Threshold Detectors

Power Supplies

Multi-meters
