PRODUCT HIGHLIGHTS
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
