ADR1500 is a low cost, 2-terminal (shunt), precision band gap reference from Analog Devices. It provides an accurate 1.2875 V output for input currents between 50 μA to 10 mA.
The ADR1500 is a 2‑terminal precision band‑gap voltage reference that delivers a stable 1.2875 V output for input currents from 50 pA to 10 mA. Its low minimum operating current makes it ideal for battery‑powered instrumentation, while the wide current range supports high‑current applications.
The device is supplied in a compact SC70 surface‑mount package and operates from –40 °C to +85 °C (specified) and –55 °C to +125 °C (operating). It includes ESD protection, low output noise, and fast turn‑on settling, making it suitable for data‑acquisition systems, medical equipment, and automotive electronics.
