Figure 3. Reverse Voltage Temperature Drift Distribution The AD15801 is a low cost, 2-terminal (shunt), precision band
300
gap reference. It provides an accurate 1.225 V output for input currents between 50 μA and 10 mA.
250
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
TITY
design techniques have been used to minimize the nonli-

nearities in the voltage output temperature characteristics.
QU
The AD1580 is stable with any value of capacitive load.
100
The low minimum operating current makes the AD1580

Figure 4. Reverse Voltage Error Distribution 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. 1 Protected by U.S. Patent No. 5,969,657.
