GENERAL DESCRIPTIONThe AD1582, AD1583, AD1584 and AD1585 are a family of
low cost, low power, low dropout, precision bandgap references.
These designs are available as three-terminal (series) devices and
are packaged in the compact SOT-23, 3-pin, surface mount
package. The versatility of these references makes them ideal for
use in battery powered 3 V or 5 V systems where there may be
wide variations in supply voltage and a need to minimize power
dissipation.
The superior accuracy and temperature stability of the AD1582/
AD1583/AD1584/AD1585 is made possible by the precise
matching and thermal tracking of on-chip components. Patented
temperature drift curvature correction design techniques have
been used to minimize the nonlinearities in the voltage output
temperature characteristic.
These series mode devices (AD1582/AD1583/AD1584/AD1585)
will source or sink up to 5 mA of load current and operate
efficiently with only 200 mV of required headroom. This family
will draw a maximum 65 µA of quiescent current with only a
1.0 µA/V variation with supply voltage. The advantage of these
designs over conventional shunt devices is extraordinary. Valuable
supply current is no longer wasted through an input series
resistor and maximum power efficiency is achieved at all input
voltage levels.
The AD1582, AD1583, AD1584 and AD1585 are available in
two grades, A and B, both of which are provided in the smallest
available package on the market, the SOT-23. Both grades are
specified over the industrial temperature range of –40°C to
+85°C.
TARGET APPLICATIONSPortable, Battery Powered Equipment. Notebook Comput-
ers, Cellular Phones, Pagers, PDAs, GPSs and DMMs.Computer Workstations. Suitable for use with a wide range
of video RAMDACs.Smart Industrial Transmitters.PCMCIA Cards.Automotive.Hard Disk Drives.3 V/5 V 8-Bit–12-Bit Data Converters.

AD1582–SPECIFICATIONSNOTES
1Maximum output voltage drift is guaranteed for all grades.
2Ripple Rejection over a wide frequency spectrum is shown in Figure 15.
3Measured with a capacitance load of 0.2 µF.
4Long-term stability at +125°C = 1600 ppm/1000 hours.
5Hysteresis is defined as the change in the 25°C output voltage, caused by bringing the device to +85°C, taking a 25°C measurement and then bringing it to –40°C, followed
by another 25°C measurement. Refer to Figure 12.
6The operating temperature range is defined as the temperature extremes at which the device will still function. Parts may deviate from their specified performance outside
the specified temperature range.

NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause
permanent damage to the device. This is a stress rating only; functional operation
of the device at these or any other conditions above those indicated in the
operational section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2Specification is for device in free air at 25°C: SOT-23 Package: θJA = 300°C/W.
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD1582/AD1583/AD1584/AD1585 feature proprietary ESD protection circuitry,
permanent damage may occur on devices subjected to high energy electrostatic discharges.
Therefore, proper ESD precautions are recommended to avoid performance degradation or loss
of functionality.

PACKAGE BRANDING INFORMATIONFour marking fields identify the device generic, grade and date
of processing. The first field is the product identifier. A “2/3/4/5”
identifies the generic as the AD1582/3/4/5. The second field
indicates the device grade; “A” or “B.” In the third field a
numeral or letter indicates the calendar year; “7” for 1997...,
“A” for 2001... The fourth field uses letters A-Z to represent a
two week window within the calendar year, starting with “A” for
the first two weeks of January.
