ADR1581ARTZ

参考电压 1.25V Micropower Precision Shunt

1.25 V Micropower, Precision Shunt  Voltage Reference

GENERAL DESCRIPTION ADR1581ARTZ

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.

The superior accuracy and stability of the ADR1581 is made  possible by the precise matching and thermal tracking of onchip  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.
