Mofetoleli oa data ke sesebelisoa, sesebelisoa, hape ke karolo ea elektroniki. Mosebetsi oa eona o ka sehloohong ke ho fetolela mefuta e meng ea matšoao a matla a motlakase ho ea ho mofuta o mong, 'me e ka fetolela mofuta o mong oa lets'oao la matla a motlakase ho a mang. Phetoho ea data e ka aroloa ka mekhahlelo e 'meli e meholo: phetoho ea lets'oao la matla a motlakase le phetoho ea lets'oao la matla a motlakase. E latelang ke kenyelletso e qaqileng ea AMEYA360 Electronic Component Purchasing Network: molao-motheo oa motheo oa ho sebetsa le mokhoa oa ho sebelisa li-converter tsa data.

I. Molao-motheo oa Mosebetsi oa Bafetoleli ba Boitsebiso 

Molao-motheo oa ts'ebetso oa sesebelisoa sa data ke ho fetolela matshwao a dijithale hore e be matshwao a analog kapa matshwao a analoge hore e be matshwao a dijithale. Lipontšo tsa Digital li emeloa ke binary coding; mohlala, 8-bit binary coding e ka fetola maemo a 256 a fapaneng hore e be lipontšo tsa digital. Ha o fetolela matšoao a dijithale ho matšoao a analog, mofetoleli oa data o bapisa lets'oao la dijithale le voltage ea litšupiso ebe o fetola sephetho hore e be lets'oao la analog. Ka lehlakoreng le leng, ha u fetolela matšoao a analog ho matšoao a dijithale, converter ea data e bapisa lets'oao la analog le voltage ea referense ebe e fetola sephetho hore e be lets'oao la dijithale.

II. Mefuta e fapaneng ea Bafetoleli ba Lintlha

Ho na le mefuta e fapaneng ea li-converter tsa data, ho kenyelletsa:

1. Non-inverting Proportional Amplifier (INA): INA ke amplifier ea motheo e sa feto-fetoheng e fetolang matšoao a kenyeletso hore e be lipontšo tsa tlhahiso, 'me ntlha ea eona ea amplification e ka behoa ka letsoho. INA e sebelisoa haholo lits'ebetsong tsa ho fumana le ho holisa data.

2. Inverting Proportional Amplifier (OTA): OTA ke inverting proportional amplifier e fetolang matšoao a kenyeletso hore e be lipontšo tsa tlhahiso, 'me ntlha ea eona ea amplification e ka behoa ka letsoho. OTA e sebelisoa haholo ts'ebetsong ea matšoao a dijithale le lits'ebetsong tsa puisano tsa dijithale.

3. Non-inverting Proportional-Integral Amplifier (INAI): INAI ke amplifier e sa fetoleng proportional-integral amplifier e fetolang matšoao a kenyeletso hore e be lipontšo tsa tlhahiso, e nang le mochine o hlophisitsoeng ka letsoho, le ho tsitsisa pontšo ea tlhahiso ka ho kopanya. INAI e sebelisoa haholo lits'ebetsong tsa ho fumana le ho holisa data.

4. Inverting Proportional-Integral Amplifier (OTAI): OTAI ke inverting proportional-integral amplifier e fetolang matšoao a kenyeletso hore e be lipontšo tsa tlhahiso, ka mochine oa amplification o behiloeng ka letsoho, 'me o tsitsisa pontšo ea tlhahiso ka ho kopanya. OTAI e sebelisoa haholo ts'ebetsong ea matšoao a dijithale le lits'ebetsong tsa puisano tsa dijithale.

5. Dual-Channel Converter (DCD): DCD ke mochine o fetolang li-channel tse peli tse fetolelang lipontšo tsa digital ho lipontšo tsa analog kapa lipontšo tsa analog ho lipontšo tsa digital. DCD e sebelisoa haholo puisanong ea dijithale le lits'ebetsong tsa likhomphutha.

III. Mokhoa oa ho Sebelisa Data Converter

Mofetoleli oa data o ka sebelisoa ho fetolela matshwao a dijithale ho matshwao a analoge kapa matshwao a analoge ho matshwao a dijithale. Mehato e latelang ke e bonolo:

(1) Etsa qeto ea mofuta oa sesebelisoa sa data se tla sebelisoa.

(2) Lokisa sesebelisoa sa data ho fetolela matšoao a dijithale ho matšoao a analog kapa matšoao a analog ho matšoao a dijithale.

(3) Kopanya lets'oao la ho kenya lithapo tsa ho kenya tsa data converter.

(4) Hokela lets'oao la tlhahiso ho amplifier kapa romella lets'oao ho lisebelisoa tse ling bakeng sa ts'ebetso e tsoelang pele.

(5) Lekanya lets'oao la tlhahiso ea converter ho netefatsa hore e kopana le matšoao a ts'ebetso a lebelletsoeng.
