The AD1580ART-REEL7 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 AD1580ART-REEL7 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 AD1580ART-REEL7 is stable with any value of capacitive load.
The low minimum operating current makes the AD1580ART-REEL7 ideal for use in battery-powered 3 V or 5 V systems. However, the wide operating current range means that the AD1580ART-REEL7 is extremely versatile and suitable for use in a wide variety of high current applications.
The AD1580ART-REEL7 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.
