Product Summary

The ad581th/883b is a 3-pin, temperature compensated, monolithic, band gap voltage reference that provides a precise 10.00 V output from an unregulated input level ranging from 12 V to 30 V. The ad581th/883b is recommended for use as a reference for 8-, 10- or 12-bit digital-to-analog converters (DACs) that require an external precision reference. Laser wafer trimming (LWT) is used to trim both the initial error at +25°C as well as the temperature coefficient, resulting in high precision performance previously available only in expen-sive hybrids or oven regulated modules. The 5 mV initial error tolerance and 5 ppm/°C guaranteed temperature coefficient of the ad581th/883b is available in a monolithic voltage reference.
