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

Incazelo

Amadivayisi we-MCP3422, MCP3423 kanye ne-MCP3424 (MCP3422/3/4) angumsindo ophansi nokunemba okuphezulu kwe-18-Bit delta-sigma analog-to-digital (ΔΣ A/D) amalungu omndeni okuguqula i-MCP342X evela ku-Microchip Technology Inc. Lawa madivayisi angaguqula okokufaka kwe-analog kube amakhodi edijithali anokulungiswa okungafika kwamabhithi ayi-18.I-voltage yereferensi esebhodini engu-2.048V inika amandla ububanzi bokufaka obungu-± 2.048V ngokuhlukile (ububanzi besikali esigcwele = 4.096V/PGA).Lawa madivayisi angakhipha imiphumela yokuguqulwa kwe-analog kuya kwedijithali ngamanani angu-3.75, 15, 60, noma amasampuli angu-240 ngomzuzwana kuye ngokuthi izilungiselelo zebhithi yokucushwa ezilawulekayo zisebenzisa i-serial interface ye-I2C enezintambo ezimbili.Phakathi nokuguqulwa ngakunye, idivayisi ilinganisa i-offset futhi izuze amaphutha ngokuzenzakalelayo.Lokhu kunikeza imiphumela enembile yokuguqulwa esuka ekuguquleni iye ekuguquleni phezu kokuhluka kwezinga lokushisa nokuguquguquka kokunikezwa kwamandla.Umsebenzisi angakhetha inzuzo ye-PGA engu-x1, x2, x4, noma x8 ngaphambi kokuthi ukuguqulwa kwe-analog kuya kudijithali kwenzeke.Lokhu kuvumela amadivayisi we-MCP3422/3/4 ukuthi aguqule isignali yokokufaka ebuthaka kakhulu enokulungiswa okuphezulu.Amadivayisi we-MCP3422/3/4 anezinhlobo ezimbili zokuguqula: (a) Imodi yokuguqulwa kwe-One Shot kanye (b) nemodi yokuguqula eqhubekayo.Kumodi yokuguqula ye-One Shot, idivayisi yenza ukuguqulwa okukodwa futhi ingena kumodi yokulinda yamanje ephansi ngokuzenzakalelayo ize ithole omunye umyalo wokuguqula.Lokhu kunciphisa ukusetshenziswa kwamanje kakhulu ngezikhathi zokungenzi lutho.Kumodi yokuguqula eqhubekayo, ukuguqulwa kwenzeka ngokuqhubekayo ngesivinini esimisiwe sokuguqula.Idivayisi ibuyekeza ibhafa yayo yokukhipha ngedatha yakamuva yokuguqulwa.
