The AD580 is a three-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 thinfilm 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 V. In addition, the low quiescent current drain of 1.5 mA max offers a clear advantage over classical Zener techniques. |
