GeneralDescription TheADC0808,ADC0809dataacquisitioncomponentisa monolithicCMOSdevicewithan8-bitanalog-to-digitalcon- verter,8-channelmultiplexerandmicroprocessorcompatible controllogic.The8-bitA/Dconverterusessuccessiveap- proximationastheconversiontechnique.Theconverterfea- turesahighimpedancechopperstabilizedcomparator,a 256Rvoltagedividerwithanalogswitchtreeandasucces- siveapproximationregister.The8-channelmultiplexercan directlyaccessanyof8-single-endedanalogsignals. Thedeviceeliminatestheneedforexternalzeroand full-scaleadjustments.Easyinterfacingtomicroprocessors isprovidedbythelatchedanddecodedmultiplexeraddress (R) inputsandlatchedTTLTRI-STATEoutputs. ThedesignoftheADC0808,ADC0809hasbeenoptimized byincorporatingthemostdesirableaspectsofseveralA/D conversiontechniques.TheADC0808,ADC0809offershigh speed,highaccuracy,minimaltemperaturedependence,ex- cellentlong-termaccuracyandrepeatability,andconsumes minimalpower.Thesefeaturesmakethisdeviceideally suitedtoapplicationsfromprocessandmachinecontrolto consumerandautomotiveapplications.For16-channelmul- tiplexerwithcommonoutput(sample/holdport)see ADC0816datasheet.(SeeAN-247formoreinformation.)， 大小：293 KB
