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 A 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 tech-

nology 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 avail-

able in a metal can (H-02) package. The AD589J is also available

in an 8-lead SOIC package.
