FEATURES Laser-trimmed to high accuracy: 2.500 V ±0.4% 3-terminal device: voltage in/voltage out Excellent temperature stability: 10 ppm/°C (AD580M, U) Excellent long-term stability: 250 μV (25 μV/month) Low quiescent current: 1.5 mA maximum Small, hermetic IC package: TO-52 can MIL-STD-883 compliant versions available GENERAL DESCRIPTION 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.
