PRODUCT DESCRIPTION
The AD589 is a two-terminal, low cost, temperature compensated bandgap voltage reference which provides a fixed 1.23 V output voltage for input currents between 50 µA and 5.0 mA.
The high stability of the AD589 is primarily dependent upon the matching and thermal tracking of the on-chip components. Analog Devices’ precision bipolar processing and thin-film technology combine to provide excellent performance at low cost.
