AD580It is a three-lead, low cost, temperature compensated bandgapVoltage referenceA fixed 2.5 V output can be provided from a 4.5 V to 30 V input. The unique combination of advanced circuit design and laser-wafer trimmed thin-film resistors results in an initial tolerance of ±0.4%, temperature stability of better than 10 ppm/°C, and long-term stability of better than 250 μV. In addition, the maximum quiescent current is as low as 1.5 mA, which offers significant advantages over conventional Zener technology.
The AD580 is recommended as a stable reference for all 8-, 10-, and 12-bit DACs that require an external reference. In addition, the device's wide input range allows it to operate from a 5 V logic supply, making it ideal for digital panel meters or any application with a single logic supply.
The AD580J/K/L/M is specified over the 0°C to +70°C temperature range and the AD580S/T/U over the extended temperature range of -55°C to +125°C.
