PRODUCT DESCRIPTION

The AD580 is a three-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 thin­film 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-, 10­and 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.

PRODUCT HIGHLIGHTS

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 con­tain 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.
