The AD589 is a two-terminal, low cost, temperature compensated bandgap voltage reference which 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. Analog Devices' precision bipolar processing and thin-film technology combine to provide excelent performance at low cost. Additionally, the active circuit produces an output impedance ten times lower than 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, K, L and M grades are specified for 0°C to +70°C operation, while the S, T, and U grades are rated for the full -55°C to +125°C temperature range. All grades are available in a metal can (H-02A) package. The AD589J is also available in an 8-pin SOIC package. * Superior Replacement for Other 1.2 V References * Wide Operating Range: 50 µA to 5 mA * Low Power: 60 µW Total PD at 50 µA * Low Temperature Coefficient: 10 ppm/°C Max, 0°C to 70/°C (AD589M) https://elecena.pl/product/17777800/two-terminal-ic-1-2-v-reference 2021-04-19 https://elecena.pl/product/17777800/two-terminal-ic-1-2-v-reference 2025-01-21
