The AD1586, AD1587, AD1588, and AD1589 are a family of 1. Portable, Battery-Powered Equipment:
low cost, low power, precision bandgap references. They are

available as two-terminal (shunt) devices and are packaged in the GPS', and DMM's.
compact SOT-23. These references provide accurate output
voltages for input currents between 50µA and 10mA.
2. Computer Workstations:
Suitable for use with a wide range of video RAMDACs.
3. Smart Industrial Transmitters.
The AD1586/7/8/9's superior accuracy and temperature stability
are made possible by the precise matching and thermal tracking 4. PCMCIA Cards.
of on-chip components. Patented temperature drift curvature
correction design techniques have been used to minimize the
nonlinearities in the voltage output temperature characteristic.
6. Hard Disk Drives.
7. 3 V / 5 V 8-12 Bit Data Converters.
The low minimum operating currents of the AD1586/7/8/9 make
these references ideal for use in battery powered 3V or 5V
systems, where there is a need to minimize power dissipation.
With their wide input current ranges, however, these designs are
extremely versatile and suitable for use in a variety of high
current applications. In addition, their tiny packaging and
inherent stability under all values of capacitive load, makes the
AD1586/7/8/9 family of references ideal for space critical
The AD1586, AD1587, AD1588, and AD1589, 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
