MCP331 Abaguquli be-Analog-to-Digital
Amadivaysi e-MCchip a-MCP331 afaka okokufaka okuphelele okuhlukile, ukusebenza okuphezulu, nokusetshenziswa kwamandla aphansi kwiphakheji elincane
Amadivayisi we-Microchip & rsquo; s sakwa-MCP331x angama-16-bit, a-14-bit, a-12-bit ayingqayizivele, isiteshi esisodwa se-Msps nama-500 kSPS abaguquguquli be-analog-to-digital (ama-ADC) asebenzisa amandla asezingeni eliphansi nokusebenza okuphezulu, besebenzisa okulandelanayo isakhiwo sokubhalisa (approximative rejection) (SAR). Amadivayisi asebenza nge-2.5 V kuya ku-5.1 V reference yangaphandle (VREF) esekela ububanzi obubanzi bokufaka ububanzi obubanzi kusukela ku-0 V ukuya ku-VREF. I-reference voltage setting isuke ingazimele nge-analog voltage supply (AVDD) futhi liphakeme kune-AVDD. Ukukhishwa kokukhipha kuyatholakala ngokusebenzisa i-interface elula ye-SPI ehambelana ne-3-wire elula ukuyisebenzisa. Lawa madivayisi anesampuli se-1 M / yesibili, isiteshi esisodwa sokufakwayo, ukusetshenziswa kwamandla aphansi (0.8 & micro; A standby ejwayelekile, 1.6 mA esebenzayo), futhi unikezwa ngephakheji le-MSOP le-10-pin. I-ADCs ye-MCP331 ifaka okokufaka okuphelele okuhlukile, ukusebenza okuphezulu, nokusetshenziswa kwamandla aphansi kuphakheji encane. Lesi sici sici esicebile senza le mikhiqizo ifanele kahle izinhlelo zokusebenza ezibhekene nebhethri nezinhlelo zokusebenza zokuthola idatha ezikude ezifana ne-instrumentation yezokwelapha, ukulawulwa kwezimoto, imishini yokuhlola, kanye nemishini yamandla wokushintsha.
- Isilinganiso sesampula (i-throughput):
- MCP33131 / 21 / 11-10: 1 Msps
- MCP33131 / 21 / 11-05: 500 kSPS
- Isixazululo se-16-bit / 14-bit / 12-bit kungekho amakhodi alahlekile
- Akukho okukhipha kamuva
- I-wide range voltage range:
- I-voltage yokunikezwa kwe-Analog (AVDD): 1.8 V
- I-Digital input / output output voltage (DVIO): 1.7 V kuya ku 5.5 V
- Isithenjwa sangaphandle (VREF): 2.5 V kuya ku-5.1 V
- Ukusebenza kokufaka ukungafani kwamanye amazwe ngokucushwa okukodwa:
- Ukufaka ububanzi bezinga eliphelele: 0 V kuya ku-VREF
- Izinketho zephakheji: MSOP-10 no-TDFN-10
- Ukusetshenziswa kwe-ultra-low yamanje (okujwayelekile):
- Ngesikhathi sokuthenga okufakwayo (kokubekwe eceleni): ~ 0.8 & micro; A
- Ngesikhathi sokuguqulwa:
- MCP331x1-10: ~ 1.6 mA
- MCP331x1-05: ~ 1.4 mA
- Ukuxhumana kwe-serial ehambisanayo ye-SPI:
- Isilinganiso sewashi le-SCLK: kufika ku-100 MHz
- I-ADC ukuzilinganisela kwamaphutha we-offset, inzuzo, nokulingana:
- Phakathi namandla-up (okuzenzakalelayo)
- Ukufunwa nge-oda ngomyalo womsebenzisi & rsquo; s ngesikhathi sokusebenza okujwayelekile
- I-AEC-Q100 iqeqeshiwe:
- Ukushisa kwebanga 1: -40 & deg; C kuya + 125 & deg; C
- Ukuthengwa kwedatha ecacile
- Izinsimbi zokwelapha
- Imishini yokuhlola
- Imishini yokuphathwa kwebhethri yemoto
- Izicelo zokulawula izimoto
- Izinhlelo zokunikezela kwamandla wokushintsha
- Imishini enikwe amandla ebhetri
