GENERAL DESCRIPTION Figure 2. Reverse Voltage Temperature Drift Distribution The ADR15811 is a low cost, 2-terminal (shunt), precision band gap reference. It provides an accurate 1.250 V output for input currents between 60 μA and 10 mA. 100 OUTPUT ERROR (mV) QUANTITY –5 –4 –3 –2 –1 0 1 2 3 4 5 06672-003 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 3 V 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 current applications. Figure 3.
