The AD589 is a 2-terminal device that delivers a constant band gap voltage reference that provides a fi xed 1.23 V output reference voltage for a wide range of input current. voltage for input currents between 50 A and 5.0 mA. 2. Output impedance of 0.6 and temperature coeffi cients as The high stability of the AD589 is primarily dependent upon low as 10 ppm/°C ensure stable output voltage over a wide the matching and thermal tracking of the on-chip components. range of operating conditions.

Floating operation is also possible. Additionally, the active circuit produces an output impedance 10 4. The AD589 will operate with a total current as low as 50 A lower than the typical low-TC Zener diodes. This feature allows (60 W total power dissipation), ideal for battery-powered operation with no external components required to maintain full instrument applications. accuracy under changing load conditions. 5. The AD589 is an exact replacement for other 1.2 V references, The AD589 is available in seven versions. The AD589J, AD589K,
