GENERAL DESCRIPTION
The AD1580 1 is a low cost, 2-terminal (shunt), precision band
gap reference. It provides an accurate 1.225 V output for input
currents between 50 μA and 10 mA.
The superior accuracy and stability of the AD1580 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 nonli-
nearities in the voltage output temperature characteristics.
The AD1580 is stable with 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 the SOT-23 and SC70 packages, the smallest
surface-mount packages available. Both grades are specified
over the industrial temperature range of ?40°C to +85°C.
