Amasekethe wokusekela ukondla inzwa afakiwe, futhi isilinganiso siyi -ometometric - i-amplifier yesigaba esinezinhlelo ezimbili ezingahlelelwa ikwazi ukwamukela izinzwa kusuka ku-1mV / V kuze kufike ku-500mV / V (500Ω kuya ku-60kΩ).
Umthombo wamanje we-on-chip futhi uvumela izinzwa ezibandakanya ukumelana ne-Pt100 platinum kanye nama-thermometer wohlobo lwe-diode ukuthi kufundwe, futhi kufakwe inzwa yokushisa ye-on-chip.
Imiphumela ingaba nge-SPI (10MHz), mina2C (ejwayelekile, esheshayo nejubane eliphezulu) noma a I2Ifomethi ethathwe ngocingo olulodwa eyenziwe ngo-C engu-100kHz ebizwa nge-'OWI 'ngamaRenesas.
Idatha ye-OWI ingathunyelwa emuva ngokusebenzisa i-4mA iye ku-20mA yamanje-loop esebenza noma yikuphi phakathi kwe-7V ne-48V kusetshenziswa i-npn modulation transistor yangaphandle. Ukusebenza nge-JFT yangaphandle, kunikezwa amasekethe angaphakathi ukuthola ujantshi kagesi we-5V we-chip kusuka kuluphu wamanje.
Kukhona futhi nokukhishwa kwe-analogue - okungatholakali ngqo kusuka kusiginali yokufaka, kepha kusuka kokukhipha kwedijithali kweprosesa yokulungisa eyakhiwe kabusha nge-16bit ADC. I-Absolute (0 -10V) namandla we-ratiometric, i-loop yamanje, noma ukuphazamisa imiphumela ye-analogue kuyasekelwa.
Ukusebenza kwe-Chip kungenye yezindlela ezintathu eziyisisekelo
Imodi yokulala inconyelwa izinzwa ngokukhipha kwedijithali kuphela. Isimo se-Idle sifakwa ngokuzenzakalela ngemuva kokukhishwa komyalo wokusetshenziswa okuncane kwamanje, ngenkathi isikhombimsebenzisi sihlala silalele ukwamukela imiyalo.
Kuvuka ngemuva kokuthola umyalo ovumelekile, kukhishwe, kunikeze imiphumela kusixhumi esibonakalayo sedijithali, bese kubuyela kokungenzi lutho ngemuva kokulanda idatha. Ukulanda idatha okuphindaphindiwe akusekelwa, futhi i-analogue outpt.
Imodi ye-Command ilungele kakhulu ukuhlolwa, ukuhlolwa, nokulinganiswa. Yonke imiyalo iyatholakala, kokubili imiphumela yedijithali ne-analog iyasekelwa, futhi yonke imisebenzi iyatholakala. Ukuxhumana okwenzeka kabusha nokuqhubekayo kwedijithali kuyatholakala.
Imodi ye-cyclic iyazimela, izilinganiso zenzwa ziphindaphindwe ngokuzenzakalela futhi zicutshungulwa zibe izibuyekezo zokukhipha (idigital noma i-analogue noma zombili). Le modi inconyelwa izinhlelo zokusebenza zokukhipha i-analogue. Izinga lokukala (yingakho izinga lokubuyekezwa kokukhipha) liyalungiseka.
Ukusebenza kungaphezu kuka-2.7V kuye ku-5.5V (7V kuye ku-48V nge-JFET yangaphandle) kanye no -40 ° C kuye ku-125 ° C.
Ukupakisha kufakwa ku-wafer noma i-4 x 4mm QFN enezikhala ezinamanzi zokuhlola ukugeleza kabusha.
Izicelo zibonwa ngaphambili ekucindezelekeni, ekuhambeni, nasekuzweleni kwezinga, inqubo ezishintshayo, i-automation yefektri, izimpahla ezimhlophe, umoya opholisayo, izikali ezinesisindo, ukuqapha umfutho wegazi kanye nabaqaphi bezempilo
