I-ADE7913ARIZ IC ADC/ENERGY MEAS 24BIT 20SOIC

Incazelo

Ama-ADE7912/ADE79131 ahlukanisiwe, ama-3-channel Σ-Δ ADCs we-polyphase energy metering applications kusetshenziswa izinzwa zamanje ze-shunt.Ukuhlukaniswa kwedatha namandla kusekelwe kubuchwepheshe be-Analog Devices, Inc., i-iCoupler®.I-ADE7912 inama-ADC amabili angama-24, kanti i-ADE7913 ihlanganisa ama-ADC amathathu.I-ADC yamanje ihlinzeka ngesilinganiso esingu-67 dB sesiginali kuya kumsindo ngaphezu komkhawulokudonsa wesignali ongu-3 kHz, kuyilapho ama-voltage ADCs ehlinzeka nge-SNR engu-72 dB ngaphezu komkhawulokudonsa ofanayo.Isiteshi esisodwa sinikezelwe ekulinganiseni amandla kagesi ku-shunt lapho i-shunt isetshenziselwa ukuzwa kwamanje.Kuze kufike kumashaneli amabili engeziwe anikezelwe ekukaleni ama-voltage, ngokuvamile azwakala kusetshenziswa ama-resistor dividers.Ishaneli eyodwa kagesi ingasetshenziswa ukukala izinga lokushisa lokufa ngenzwa yangaphakathi.I-ADE7913 ihlanganisa iziteshi ezintathu: ishaneli eyodwa yamanje kanye namashaneli amabili kagesi.I-ADE7912 inesiteshi esisodwa sikagesi kodwa iyafana ne-ADE7913.
