参考电压 2-Terminal IC 1.2V REF
Product Details
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.
