GENERAL DESCRIPTION
The AD1580 is a low cost, two-terminal (shunt), precision
bandgap reference. It provides an accurate 1.225 V output for
input currents between 50
bandgap reference. It provides an accurate 1.225 V output for
input currents between 50
µ
A and 10 mA.
The AD1580’s superior accuracy and stability is made possible
by the precise matching and thermal tracking of on-chip
components. Proprietary curvature correction design techniques
have been used to minimize the nonlinearities in the voltage
output temperature characteristics. The AD1580 is stable with
any value of capacitive load.

any value of capacitive load.
The low minimum operating current makes the AD1580 ideal
for use in battery powered 3 V or 5 V systems. However, the
wide operating current range means that the AD1580 is
extremely versatile and suitable for use in a wide variety of high
current applications.

The AD1580 is available in two grades, A and B, both of which
are provided in an SOT-23 package, the smallest surface mount
package available on the market. Both grades are specified over
the industrial temperature range of –40
