AD1580ART-R2

Voltage Reference Overview

The AD1580ART-R2 is a micropower, precision shunt voltage reference manufactured by Analog Devices Inc. It provides an accurate output of 1.225 V with a maximum initial accuracy of ±0.1% and a temperature drift of ±50 ppm/°C. The device operates within a wide current range from 50 µA to 10 mA and features low broadband noise of 20 µV rms (10 Hz to 10 kHz). It is housed in a compact SOT-23 package and functions over an industrial temperature range of −40°C to +85°C.

Voltage Reference Feature Summary
