AD589JRZ

AD589 is a 2-terminal, low cost, temperature compensated band gap voltage reference that provides a fixed 1.23V output voltage for input currents between 50µA and 5mA. The high stability of the device 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. Additionally, the active circuit produces an output impedance 10X lower than the typical low-TC Zener diodes. This feature allows operation with no external components required to maintain full accuracy under changing load conditions.
