PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The AD580 is a three-terminal, low cost, temperature compen-

sated, bandgap voltage reference which provides a fixed 2.5 V

output for inputs between 4.5 V and 30 V. A unique combina-

tion 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 max offers a clear advantage

over classical Zener techniques.

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

and 12-bit D-to-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.

1. Laser-trimming of the thin-film resistors minimizes the

AD580 output error. For example, the AD580L output

tolerance is

10 mV.

2. The three-terminal voltage in/voltage out operation of

the AD580 provides regulated output voltage without

any external components.

3. 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-volt input

makes the AD580 an ideal choice for systems that con-

tain a single logic power supply.

4. 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.

5. The low quiescent current drain of the AD580 makes it

ideal for CMOS and other low power applications.

6. The AD580 is available in versions compliant with

MIL-STD-883. Refer to the Analog Devices Military

Products Databook or current AD580/883B data sheet

for detailed specifications.
