Product Description

Product Details
The ADR1581 is a low cost, 2-terminal (shunt), precision band gap reference. It provides an accurate 1.25 V output for input currents between 60 UA and 10 mA.
The superior accuracy and stability of the ADR1581 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 ADR1581 is stable with any value of capacitive load.
The low minimum operating current makes the ADR1581 ideal for use in battery-powered 3V or 5 V systems. However, the wide operating current range means that the ADR1581 is extremely versatile and suitable for use in a wide variety of high vurrent applications.
The ADR1581 is available in two grades, A and B, both of which are provided in the SOT23 and SC70 packages, the smallest surface-mount packages available. Both grades are specified over the industrial temperature range of -40°C to +85°C.
