Inkcazo
Izixhobo ze-MCP3422, MCP3423 kunye ne-MCP3424 (MCP3422/3/4) yingxolo ephantsi kunye nokuchaneka okuphezulu kwe-18-Bit delta-sigma analog-to-digital (ΔΣ A/D) amalungu osapho oluguqulelayo lwe-MCP342X series evela kwi-Microchip Technology Inc. Ezi zixhobo zinokuguqula amagalelo e-analog kwiikhowudi zedijithali kunye ne-18 bits yesisombululo.I-on-board 2.048V i-voltage yereferensi yenza uluhlu lwegalelo lwe-± 2.048V ngokwahlukileyo (uluhlu olupheleleyo lwesikali = 4.096V / PGA).Ezi zixhobo zinokukhupha iziphumo zokuguqulwa kwe-analog-to-digital kwimilinganiselo ye-3.75, i-15, i-60, okanye i-240 iisampulu ngesekhondi ngokuxhomekeke kumsebenzisi olawulekayo useto lwe-bit yoqwalaselo usebenzisa i-interface ye-serial ye-I2C.Ngexesha loguqulelo ngalunye, isixhobo silinganisa i-offset kwaye sifumane iimpazamo ngokuzenzekelayo.Oku kubonelela ngeziphumo zoguqulo ezichanekileyo ukusuka kuguqulo ukuya kuguqulo ngaphezu kokwahluka kweqondo lobushushu kunye nokuguquguquka konikezelo lwamandla.Umsebenzisi unokukhetha inzuzo ye-PGA ye-x1, x2, x4, okanye x8 phambi kokuba ukuguqulwa kwe-analog-to-digital kwenzeke.Oku kuvumela izixhobo ze-MCP3422/3/4 ukuba ziguqule isignali yegalelo ebuthathaka kakhulu ngesisombululo esiphezulu.Izixhobo ze-MCP3422/3/4 zineendlela ezimbini zokuguqula: (a) Imowudi ye-One-Shot Conversion kunye (b) Imo yokuGuqulwa ngokuqhubekayo.Kwimo yokuguqula i-One-Shot, isixhobo senza uguqulelo olunye kwaye singene kwimo yokulinda yangoku esezantsi ngokuzenzekelayo de sifumane omnye umyalelo wokuguqula.Oku kunciphisa ukusetyenziswa kwangoku kakhulu ngexesha lokungenzi nto.Kwimo yoguqulo oluqhubekayo, uguqulo lwenzeka ngokuqhubekayo kwisantya esimisiweyo sokuguqula.Isixhobo sihlaziya i-buffer yemveliso ngeyona datha yamva nje yoguqulo.
