AD589
APPLICATION INFORMATION
??
THE AD589 FUNCTIONS AS A 2-TERMINAL SHUNT-TYPE REGULATOR. IT
PROVIDES A CONSTANT 1.23 V OUTPUT FOR A WIDE RANGE OF INPUT
CURRENT FROM 50 A TO 5 MA. FIGURE 5 SHOWS THE SIMPLEST CON-
fi GURATION FOR AN OUTPUT VOLTAGE OF 1.2 V OR LESS. NOTE THAT NO
FREQUENCY COMPENSATION IS REQUIRED. IF ADDITIONAL fi LTERING IS
DESIRED FOR ULTRALOW NOISE APPLICATIONS, MINIMUM RECOMMENDED
CAPACITANCE IS 1000 PF.

THE AD589 CAN ALSO BE USED AS A BUILDING BLOCK TO GENERATE
OTHER VALUES OF REFERENCE VOLTAGE. FIGURE 6 SHOWS A CIRCUIT THAT
PRODUCES A BUFFERED 10 V OUTPUT. TOTAL SUPPLY CURRENT FOR THIS
CIRCUIT IS APPROXIMATELY 2 MA.

THE AD589 ALSO IS USEFUL AS A REFERENCE FOR CMOS MULTIPLYING
DACS, SUCH AS THE AD7533. THESE DACS REQUIRE A NEGATIVE
REFERENCE VOLTAGE IN ORDER TO PROVIDE A POSITIVE OUTPUT RANGE.

THE LOW POWER OPERATION OF THE AD589 MAKES IT IDEAL FOR USE IN
BATTERY-OPERATED PORTABLE EQUIPMENT. IT IS ESPECIALLY USEFUL AS A
REFERENCE FOR CMOS ANALOG-TO-DIGITAL CONVERTERS. FIGURE 7 SHOWS
THE AD589 USED IN CONJUNCTION WITH TWO POPULAR INTEGRATING TYPE
CMOS ADCS.
