The AD580 is a high precision, 2.5 V IC reference chip launched by Analog Devices. The chip adopts a 3-pipe structure and integrates a precision temperature compensation circuit. The output voltage is 2.5V, and the input voltage range is 4.5-30V. AD580 has excellent temperature stability and long-term stability. Its output voltage changes within ±0.4% in the working temperature range. At 25℃, the long-term stability is 25μV/month.
The AD580 is a 3-terminal, low-cost, temperature-compensated bandgap voltage reference that provides a fixed 2.5 V output for input voltages between 4.5 V and 30 V. It combines advanced circuit design with laser-wafer trimmed thin film resistors to achieve an initial tolerance of ±0.4%, a temperature stability of better than 10 ppm/°C, and long-term stability better than 250 μV.
