ADI AD589JRZ

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 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. Precision bipolar processing and thin-film technology combine to provide excellent performance at low cost. Additionally, the active circuit produces an output impedance 10× 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. The AD589 is available in seven versions. The AD589J, AD589K, AD589L, and AD589M grades are specified for 0°C to +70°C operation, while the AD589S and AD589T grades are rated for the full -55°C to +125°C temperature range. All grades are available in a metal can (H - 02) package. The AD589J is also available in an 8 - lead SOIC package.
