®ICL8069Data SheetJanuary 2004FN3172.3Low Voltage ReferenceThe ICL8069 is a 1.2V temperature-compensated voltagereference. It uses the band-gap principle to achieve excel-lent stability and low noise at reverse currents down to 50µA.Applications include analog-to-digital converters, digital-to-analog converters, threshold detectors, and voltageregulators. Its low power consumption makes it especiallysuitable for battery operated equipment.Features• Low Bias Current (Min) . . . . . . . . . . . . . . . . . . . . . . .50µA• Low Dynamic Impedance• Low Reverse Voltage• Low CostPinoutsICL8069 (SOIC)TOP VIEWOrdering InformationPARTNUMBERICL8069CCZRICL8069DCZRICL8069CCBAMAXIMUMTEMPCO0.005%/oC0.01%/oC0.005%/oCTEMP.RANGE(oC)0 to 700 to 700 to 70PACKAGESIP Package(TO-92)SIP Package(TO-92)8 Ld SOlCPKG.DWG. #Z3.05Z3.05M8.15NCNCNCV-12348765V+NCNCNCICL8069 (SIP TO-92)TOP VIEWNC1V+2V-31CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.1-888-INTERSIL or 321-724-7143|Intersil (and design) is a registered trademark of Intersil Americas Inc.Copyright © Intersil Americas Inc. 2004.

If circuit strays in excess of 200pF are anticipated, a 4.7µF shunt capacitor will ensure stability under all operating conditions.3. In normal use, the reverse voltage cannot exceed the reference voltage. However when plugging units into a powered-up test fixture, aninstantaneous voltage equal to the compliance of the test circuit will be seen. This should not exceed 20V.3ICL8069Typical Performance Curves14OUTPUT VOLTAGE CHANGE (mV)12REVERSE CURRENT (A)108-55oC6420-210µ1µ100µ1mA10mA0.20.40.60.81.01.21.4REVERSE CURRENT (A)REVERSE VOLTAGE (V)25oC,125oC1mA100mA100µ10µ125oC25oC-55oCFIGURE 1.
