PRODUCT DESCRIPTION
The AD589 is a 2-terminal, low cost, temperature compensated band gap voltage reference that provides a fixed 1.23 V output voltage for input currents between 50 uA 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.
