Analog Devices AD589 Manuals

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 μA and 5.0 mA.

The AD589 is a 2-terminal, low-cost, temperature-compensated bandgap voltage reference that provides a fixed 1.23V output voltage for input currents between 50μA and 5mA. 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. Additionally, the active circuit produces an output impedance of 0.6Ω, eliminating the need for frequency compensation.
