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.

The AD580 is recommended as a stable reference for all 8-, 10-,

and 12-bit D/A converters that require an external reference. In

addition, the wide input range of the AD580 allows operation

with 5 volt logic supplies, making the AD580 ideal for digital

panel meter applications or whenever only a single logic power

supply is available.

The AD580J, K, L, and M are specified for operation over the

0°C to +70°C temperature range; the AD580S, T, and U are

specified for operation over the extended temperature range of

–55°C to +125°C.

Laser-trimming of the thin film resistors minimizes the

AD580 output error. For example, the AD580L output

tolerance is ±10 mV.

The three-terminal voltage in/voltage out operation of the

AD580 provides regulated output voltage without any

external components.

The AD580 provides a stable 2.5 V output voltage for input

voltages between 4.5 V and 30 V. The capability to provide

a stable output voltage using a 5 V input makes the AD580

an ideal choice for systems that contain a single logic

power supply.

Thin film resistor technology and tightly controlled bipolar

processing provide the AD580 with temperature stabilities

to 10 ppm/°C and long-term stability better than 250 μV.

The low quiescent current drain of the AD580 makes it

ideal for CMOS and other low power applications.

The AD580 is available in versions compliant with MIL-

STD-883. Refer to the Analog Devices Military Products

Data Book or the current AD580/AD883B data sheet for

detailed specifications.
