MCP3424-E/SL IC ADC 18BIT SIGMA-DELTA 14SOIC

Tsanangudzo

Iyo MCP3422, MCP3423 uye MCP3424 zvishandiso (MCP3422/3/4) ndiyo yakaderera ruzha uye yakanyanya kunaka 18-Bit delta-sigma analog-to-digital (ΔΣ A/D) inoshandura nhengo dzemhuri dzeMCP342X dzakatevedzana kubva kuMicrochip Technology Inc. Midziyo iyi inogona kushandura mapipu eanalog kuita makodhi edhijitari ane anosvika gumi nemasere mabhiti ekugadziriswa.Iyo pa-bhodhi 2.048V referensi voltage inogonesa yekuisa huwandu hwe ± 2.048V zvakasiyana (yakazara chiyero chiyero = 4.096V/PGA).Midziyo iyi inogona kuburitsa analog-to-digital shanduko mhinduro pamitengo ye3.75, 15, 60, kana 240 samples pasekondi zvichienderana nemushandisi anodzoreka gadziriso dhijitari uchishandisa maviri-waya I2C serial interface.Panguva yekushandurwa kwega kwega, chishandiso chinogadzirisa offset uye kuwana zvikanganiso otomatiki.Izvi zvinopa mhedzisiro yeshanduko yechokwadi kubva pakushandurwa kuenda kushanduko pamusoro pekusiyana kwetembiricha uye kushanduka kwemagetsi.Mushandisi anogona kusarudza iyo PGA kuwana ye x1, x2, x4, kana x8 kushandurwa kweanalog-to-digital kusati kwaitika.Izvi zvinobvumira iyo MCP3422/3/4 zvishandiso kushandura isina kusimba yekuisa siginecha ine yakakwirira resolution.Midziyo yeMCP3422/3/4 ine nzira mbiri dzekushandura: (a) One-Shot Conversion mode uye (b) Continuous Conversion mode.MuOne-Shot conversion mode, mudziyo unoshandura kamwe chete uye wopinda otomatiki pane yazvino yekumira modhi kusvikira wagamuchira mumwe murairo wekutendeuka.Izvi zvinoderedza kushandiswa kwazvino zvakanyanya panguva yekusaita basa.In Continuous conversion mode, kutendeuka kunoitika nguva dzose panguva yakatarwa yekushandura kasi.Chishandiso chinogadziridza buffer yayo yekubuda neiyo yazvino kushandura data.
