Overview
The AD581JH, produced by Analog Devices Inc., is a high-precision 10 V IC voltage reference. This monolithic, temperature-compensated device is designed to provide a precise 10.00 V output from an unregulated input voltage ranging from 12 V to 30 V. The AD581JH utilizes laser wafer trimming to achieve high precision, with an initial error tolerance of ±5 mV and a temperature coefficient of 5 ppm/°C. This device is packaged in a hermetically sealed 3-pin TO-5 metal can and is suitable for a wide range of precision reference applications.
