GENERAL DESCRIPTION

The ADR01, ADR02, ADR03, and ADR06 are precision 10 V,

5 V, 2.5 V, and 3.0 V band gap voltage references featuring high

accuracy, high stability, and low power. The parts are housed in

tiny SC70-5 and TSOT-5 packages, as well as the SOIC-8

versions. The SOIC-8 versions of the ADR01, ADR02, and

REF01, REF02, and REF03. The small footprint and wide

operating range make the ADR0x references ideally suited for

general-purpose and space-constraint applications.

With an external buffer and a simple resistor network, the

TEMP terminal can be used for temperature sensing and

approximation. A TRIM terminal is provided on the devices

for fine adjustment of the output voltage.

The ADR01, ADR02, ADR03, and ADR06 are compact, low drift

voltage references that provide an extremely stable output

voltage from a wide supply voltage range. They are available in

SC70-5, TSOT-5, and SOIC-8 packages with A and B grade

selections. All parts are specified over the extended industrial

(–40°C to +125°C) temperature range.
