Isiguquli sedatha iyithuluzi, idivayisi, kanye nengxenye ye-elekthronikhi. Umsebenzi wayo oyinhloko ukuguqula ezinye izinhlobo zezimpawu zamandla kagesi zibe olunye uhlobo, futhi ingaguqula uhlobo olulodwa lwesignali yesici samandla kagesi lube olunye. Ukuguqulwa kwedatha kungahlukaniswa ngezigaba ezimbili eziyinhloko: ukuguqulwa kwesignali yamandla kagesi kanye nokuguqulwa kwesignali yesici samandla kagesi. Okulandelayo isingeniso esiningiliziwe se-AMEYA360 Electronic Component Purchasing Network: isimiso esiyisisekelo sokusebenza kanye nendlela yokusebenzisa yeziguquli zedatha.

I. Isimiso Esiyisisekelo Sokusebenza Seziguquleli Zedatha 

Umgomo oyisisekelo wokusebenza wesiguquli sedatha ukuguqula amasignali edijithali abe amasignali e-analog noma amasignali e-analog abe amasignali edijithali. Amasignali Digital amelelwa ikhodi kanambambili; isibonelo, ikhodi kanambambili engu-8-bit ingaguqula amazinga ahlukene angama-256 abe amasignali edijithali. Lapho uguqulela amasignali edijithali abe amasignali e-analog, isiguquli sedatha siqhathanisa isiginali yedijithali nevolthi yereferensi futhi siguqule umphumela ube isignali ye-analog. Ngokuphambene, lapho uguqula amasiginali e-analog abe amasignali edijithali, isiguquli sedatha siqhathanisa isignali ye-analog ne-voltage eyireferensi futhi siguqule umphumela ube isignali yedijithali.

II. Izinhlobo Ezihlukene Zokuguqulela Idatha

Kunezinhlobo ezahlukene zeziguquli zedatha, okuhlanganisa:

1. Isikhulisi Esilinganiselayo esingaguquki (INA): I-INA iyisikhulisamazwi esiyisisekelo esingaguquki esiguqula amasignali okokufaka abe amasignali okukhiphayo, futhi isici saso sokukhulisa singasethwa mathupha. I-INA isetshenziswa kakhulu ezinhlelweni zokutholwa kwedatha kanye ne-amplification.

2. I-Inverting Proportional Amplifier (OTA): I-OTA iyisikhulisamazwi esiguqulayo esilinganisa esiguqula amasignali okokufaka abe amasignali okukhiphayo, futhi isici saso sokukhulisa singasethwa mathupha. I-OTA isetshenziswa kabanzi ekucutshungulweni kwesiginali yedijithali kanye nezinhlelo zokuxhumana zedijithali.

3. Isikhulisi sesikhulisi se-Proportional-Integral esingaguquki (INAI): I-INAI iyi-amplifier engaguquki ye-proportional-integral eguqula amasignali okokufaka abe amasignali okukhiphayo, ngento yokukhulisa amandla esethwe ngesandla, futhi izinze isignali yokuphumayo ngesihlanganisi. I-INAI isetshenziswa kakhulu ezinhlelweni zokutholwa kwedatha kanye ne-amplification.

4. I-Inverting Proportional-Integral Amplifier (OTAI): I-OTAI i-inverting proportional-integral amplifier eguqula amasiginali okokufaka abe amasignali okukhiphayo, ngento yokukhulisa amandla esethwe mathupha, futhi izinze isignali yokuphumayo ngesihlanganisi. I-OTAI isetshenziswa kabanzi ekucutshungulweni kwesiginali yedijithali kanye nezinhlelo zokuxhumana zedijithali.

5. I-Dual-Channel Converter (DCD): I-DCD iyisiguquli seziteshi ezimbili esiguqula amasignali edijithali abe amasignali e-analogi noma amasignali e-analog abe amasignali edijithali. I-DCD isetshenziswa kakhulu ekuxhumaneni kwedijithali nezinhlelo zamakhompiyutha.

III. Ungayisebenzisa kanjani i-Data Converter

Isiguquli sedatha singasetshenziswa ukuguqula amasignali edijithali abe amasignali e-analog noma amasignali e-analog abe amasignali edijithali. Okulandelayo yizinyathelo ezilula:

(1) Nquma uhlobo lwesiguquli sedatha okufanele sisetshenziswe.

(2) Lungiselela isiguquli sedatha ukuze siguqule amasignali edijithali abe amasignali e-analog noma amasignali e-analog abe amasignali edijithali.

(3) Xhuma isignali yokufaka nezikhonkwane zokufaka zesiguquli sedatha.

(4) Xhuma isignali yokuphumayo ku-amplifier noma thumela isignali kwamanye amadivaysi ukuze iqhubeke nokusebenza.

(5) Linganisa isignali yokuphumayo yesiguquli ukuze uqinisekise ukuthi sihlangabezana nezinkomba zokusebenza ezilindelekile.
