ADR01（UItracompact, Precision,10.0 V Voltage References）

Introduction

The ADR01, ADR02, ADR03, and ADR06 are precision 10.0 V,5.0 V, 2.5 V, and 3.0 V, respectively, band gap voltage references featuring high accuracy, high stability, and low power consumption. The devices are housed in tiny, 5-lead SC70 and TSOT packages, as well as in 8-lead SOIC version. The SOIC version of the ADR01, ADR02, and ADR03 are drop-in replacements’ to the industry-standard REF01, REF02, and REF03.The small footprint and wide operating range make the ADR01,ADR02, ADR03, and ADR06 references ideally suited for general-purpose and space- constrained applications.

With an external buffer and a simple resistor network,the TEMP pin can be used for temperature sensing and approximation. A TRIM pin 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 a stable output voltage from a wide supply voltage range. The devices are available in 5-lead SC70 and TSOT packages and an 8-lead SOIC package with A,B, and C grade selections. All devices are specified over the extended industrial (-40°C to +125°C) temperature range. The ADR01, ADR02, ADR03, and ADR06 A grade in 8-lead SOIC are qualified for automotive applications.
