AD580*

The AD580 is a three-terminal, low cost, temperature compen-sated, bandgap voltage reference which provides a fixed 2.5 Voutput for inputs between 4.5 V and 30 V. A unique combina-tion of advanced circuit design and laser-wafer trimmed thin-film resistors provide the AD580 with an initial tolerance of±0.4%, a temperature stability of better than 10 ppm/ andlong-term stability of better than 250 µV. In addition, the low
quiescent current drain of 1.5 mA max offers a clear advantageover classical Zener techniques.

The AD580 is recommended as a stable reference for all 8-, 10-and 12-bit D-to-A converters that require an external reference.In addition, the wide input range of the AD580 allows operationwith 5 volt logic supplies making the AD580 ideal for digitalpanel meter applications or whenever only a single logic powersupply is available.
The AD580J, K, L and M are specified for operation over the0 to +70 temperature range; the AD580S, T and U arespecified for operation over the extended temperature range of55 to +125.
