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 1.5 mA maximum offers a clear advantage over classical Zener techniques.

AD580U属于集成电路（IC） > 电压基准。亚德诺半导体技术有限公司制造生产的AD580U电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。
