This document describes the features of the ADR512 1.2 V Precision Low Noise Shunt Voltage Reference, including compact size, no external capacitor required, low output noise, and high accuracy.
The ADR512 is a 1.200 V precision shunt‑mode voltage reference designed for space‑critical applications. It offers ultralow output noise (4 µV p‑p from 0.1 Hz to 10 Hz), high initial accuracy (±0.3 %), and a temperature coefficient of 60 ppm/°C, all in a 3 mm × 3 mm SOT‑23 package. The device operates without an external output capacitor and supports a wide operating current range of 100 pA to 10 mA.
Typical applications include precision data‑acquisition systems, battery‑powered portable instruments, medical devices, and industrial process‑control equipment. The ADR512 can be used as a reference for data converters, as a negative‑voltage reference, or in adjustable precision voltage source circuits when combined with an op‑amp.
