AD589JH

AD589 is a 2-terminal, low cost, temperature compensated band gap voltage reference that provides a fixed 1.23V output voltage for input currents between 50µA and 5mA. The high stability of the device 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 10X 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.

• Superior replacement for other 1.2V references
• Output voltage is 1.235V typical at (IIN = 500µA and TA = 25°C)
• Dynamic output impedance is 0.6 ohm typical at (IIN = 500µA and TA = 25°C)
• RMS noise voltage is 5µV typical at (IIN = 500µA and TA = 25°C)
• Temperature coefficient is 100ppm/°C maximum at (IIN = 500µA and TA = 25°C)
• Turn on settling time is 25µs typical at (IIN = 500µA and TA = 25°C)
• Operating current is 5mA maximum at (IIN = 500µA and TA = 25°C)
• Operating temperature is 0°C to +70°C
• Package style is metal can (TO-51)
