No guarantees for system-level compatibility are implied. SOIC-8 versions of ADR01/ADR02/ADR03 are pin-to-pin compatible with SOIC-8 versions of REF01/REF02/REF03, respectively, with the additional temperature monitoring function.

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 ADR03 are drop-in replacements1 to the industry-standard 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. Rev.
