GENERAL DESCRIPTION PRODUCT HIGHLIGHTS
The AD580 is a 3-terminal, low cost, temperature-compensated, 1. Laser-trimming of the thin film resistors minimizes the bandgap voltage reference, which provides a fixed 2.5 V output AD580 output error. For example, the AD580L output for inputs between 4.5 V and 30 V. A unique combination of tolerance is ±10 mV. advanced circuit design and laser-wafer trimmed thin film 2. The three-terminal voltage in/voltage out operation of the resistors provide the AD580 with an initial tolerance of ±0.4%, a AD580 provides regulated output voltage without any temperature stability of better than 10 ppm/°C, and long-term external components. stability of better than 250 μV. In addition, the low quiescent 3. The AD580 provides a stable 2.5 V output voltage for input current drain of 1.5 mA maximum offers a clear advantage over voltages between 4.5 V and 30 V. The capability to provide classical Zener techniques. a stable output voltage using a 5 V input makes the AD580 an ideal choice for systems that contain a single logic The AD580 is recommended as a stable reference for all 8-, 10-, power supply. and 12-bit D/A converters that require an external reference. In 4. Thin film resistor technology and tightly controlled bipolar addition, the wide input range of the AD580 allows operation processing provide the AD580 with temperature stabilities with 5 volt logic supplies, making the AD580 ideal for digital to 10 ppm/°C and long-term stability better than 250 μV. panel meter applications or whenever only a single logic power 5. The low quiescent current drain of the AD580 makes it supply is available. ideal for CMOS and other low power applications. 6. The AD580 is available in versions compliant with MIL- The AD580J, K, L, and M are specified for operation over the STD-883.
