AD1580ARTZ-REEL7 参考电压

AD1580ARTZ-REEL7

1.2 V Micropower, Precision  Shunt Voltage Reference

GENERAL DESCRIPTION

The AD1580ARTZ AD1580 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 AD1580ARTZ 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 nonlinearities  in the voltage output temperature characteristics.  The AD1580ARTZ AD1580 is stable with any value of capacitive load.
