The ADR02 are precision 5.0 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 ADR02 are drop-in replacements to the industry-standard REF02. The small footprint and wide operating range make the ADR02 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 ADR02 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 ADR02 A grade in 8-lead SOIC are qualified for automotive applications.
