MIL-STD-883 compliant versions available +E Figure 1. PRODUCT HIGHLIGHTS The AD580 is a 3-terminal, low cost, temperature-compensated,
bandgap voltage reference, which provides a fixed 2.5 V output
for inputs between 4.5 V and 30 V. A unique combination 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/°C, and long-term
stability of better than 250 μV. In addition, the low quiescent
current drain of 1.5 mA maximum offers a clear advantage over
classical Zener techniques. 1. The AD580J, K, L, and M are specified for operation over the
0°C to +70°C temperature range; the AD580S, T, and U are
specified for operation over the extended temperature range of
–55°C to +125°C. 00525-B-001 –E GENERAL DESCRIPTION The AD580 is recommended as a stable reference for all 8-, 10-,
and 12-bit D/A converters that require an external reference. In …
