AD589 2-Terminal IC 1.2 V Reference FEATURES Superior Replacement for Other 1.2 V References Wide Operating Range: 50 A to 5 mA Low Power: 60 W Total PD at 50 A Low Temperature Coefficient: 10 ppm/C Max, 0C to 70C (AD589M) 2-Terminal Zener Operation Low Output Impedance: 0.6 No Frequency Compensation Required Low Cost MIL-STD-883 Compliant Versions Available FUNCTIONAL BLOCK DIAGRAMS 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. PRODUCT HIGHLIGHTS 1. The AD589 is a 2-terminal device that delivers a constant reference voltage for a wide range of input current. 2. Output impedance of 0.6 and temperature coefficients as low as 10 ppm/°C ensure stable output voltage over a wide range of operating conditions. 3. The AD589 can be operated as a positive or negative refer- ence. Floating operation is also possible. 4. The AD589 will operate with a total current as low as 50 A (60 W total power dissipation), ideal for battery-powered instrument applications. 5. The AD589 is an exact replacement for other 1.2 V references, offering superior temperature performance and reduced sensi- tivity to capacitive loading. 6. The AD589 is available in versions compliant with MIL- STD-883. Consult factory for 883 data sheet.
