Precision Series Sub-Band Gap Voltage Reference

The ADR130 is the first family of tiny, micropower, low voltage, high precision voltage references in the industry. Featuring 0.35% initial accuracy and 25 ppm/°C of temperature drift in the tiny TSOT-23 package, the ADR130 voltage reference only requires 80 μA for typical operation. The ADR130 design includes a proprietary temperature drift curvature correction technique that minimizes the nonlinearities in the output voltage vs. temperature characteristics.

Available in the industrial temperature range of −40°C to +125°C, the ADR130 is housed in a tiny TSOT-23 package.

For 0.5 V output, tie SET (Pin 5) to VOUT (Pin 4). For 1.0 V output, tie SET (Pin 5) to GND (Pin 2).
