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