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 uA 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 excellent performance at low cost.

10 ppm/°C Max, 0°C to 70°C (AD589M)

2-Terminal Zener Operation

Low Output Impedance: 0.6 Ω

No Frequency Compensation Required

Low Cost

MIL-STD-883 Compliant Versions Available

AD589JR属于集成电路（IC） > 电压基准。亚德诺半导体技术有限公司制造生产的AD589JR电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。
