MCP331 Abaguquli be-Analog-to-Digital Converters
Izixhobo ze-MCP3 ze-MCP331 zinegalelo elihlukileyo ngokupheleleyo, ukusebenza okuphezulu kunye nokusetyenziswa kwamandla aphantsi kwiphakheji encinci
I-Microchip & rsquo; s i-MCP331x zixhobo zi-16-bit, ezi-14-bit, kunye ne-12-bit, ezine-channel 1 zakwa-Msps kunye ne-500 kSPS abaguquli-njijitjhi (i-ADC) kunye nokusetyenziswa kwamandla aphantsi kunye nokusebenza okuphezulu, kusetyenziswa ngokulandelelana ubugcisa bokubhalisa (SAR). Izixhobo zisebenza nge-2.5 V ukuya kwi-5.1 V yangaphandle inkalo (VREF) exhasa uluhlu olubanzi lwezithuba ezipheleleyo ezivela kwi-0 V ukuya kwiVREF. Isixhobo sokutshintsha i-voltage sizimeleyo kwi-analog supply supply (AVDD) kwaye liphezulu kune-AVDD. Ukukhishwa kokuphuma kuyatholakala ngokusetyenziswa okulula ukusetyenziswa kwe-SPI ehambelana ne-3-wire interface. Ezi zixhobo zinemifanekiso ye-1 M / yesibini, isiteshi esisodwa sokufakelwa kwamandla, ukusetyenziswa kwamandla aphantsi (0.8 & micro; I-standby standby, 1.6 mA esebenza ngokuqhelekileyo), kwaye inikwe kwi-packaged MSOP ye-10-pin. I-ADCs ye-MCP331 ifaka igalelo elihlukileyo ngokupheleleyo, ukusebenza okuphezulu kunye nokusetyenziswa kwamandla aphantsi kwiphakheji encinci. Isetyenzisi esinobutyebi senza ukuba le mveliso ifaneleke kwiinkqubo ezixhaswe ngebhetri kunye nezicelo zokufumana idatha ezikude ezifana nokusetyenziswa kwezixhobo zonyango, ukulawulwa kwemoto, izixhobo zokuvavanya, kunye nokunikezelwa kwamandla ombane wokutshintsha.
