Nkọwa
Ihe ngosi sekit 1383 na-egosipụta LTC2451, ihe ntụgharị analọgụ-na-dijitalụ dị elu 16 (ADC) nwere interface I2C. Ntinye bụ bipolar nwere oke Ref-to Ref+. Ihe nwe modulator sampUsoro ling na-ebelata nkezi ntinye ugbu a ka ọ na-erughị 50nA iwu nke ịdị ukwuu dị ala karịa ahụkarị delta sigma ADCs. LTC2451 dị na ngwungwu 8 pin, 3x2mm DFN ma nwee interface dị mfe iji I2C.
DC1383 bụ otu n'ime ụlọ ngosi ihe ngosi nke Linear Technology's Quick Eval™. Emebere ya ka ọ kwe ka nleba anya nke LTC2451 dị mfe yana enwere ike ijikọ ya ozugbo na akara analog nke ngwa ebumnuche mgbe ị na-eji bọọdụ USB Serial Controller DC590 yana ngwanrọ ewepụtara iji tụọ arụmọrụ. Ụgbọ elu ala ndị ahụ ekpughere na-enye ohere ntọ ala kwesịrị ekwesị iji gosipụta sekit.
