Baetapele ba 10 ba phahameng ka ho fetisisa ba li-analog lefatšeng ba bile teng joang?

Ho theosa le nalane, baetapele ba li-analog chip ba holile ho tsoa mebarakeng e meholo.China, eo hajoale e nang le 'maraka o moholo ka ho fetisisa oa semiconductor le sekhahla se phahameng sa kholo, e lebelletsoe ho pheta maemo a lebisitseng ho kholo e potlakileng ea ADENO.

Mohloli oa lintlha tsohle ke lets'oao la analog, 'me li-chips tsa analog ke lipotoloho tse kopaneng tsa analog bakeng sa ho sebetsana le matšoao a analog.Lipontšo tsa analoge ke matšoao a tsoelang pele ka nako le boholo, ha matšoao a dijithale e le matšoao a sa tsoeleng pele ka nako le boholo.Kamora hore lets'oao la kantle le fetoloe ke sensor hore e be lets'oao la motlakase, ke lets'oao la analog le ntseng le holisoa le ho tlhotluoa ka har'a sistimi e nang le chip ea analog.Letšoao la analog le sebetsitsoeng le ka hlahisoa ho sistimi ea dijithale bakeng sa ho sebetsa ka sesebelisoa sa data kapa ka kotloloho ho actuator.

Sistimi e nyalisitsoeng e tloaelehileng ea digital-to-analog e kenyelletsa mehala ea thekeng, likhomphutha tsa motho, lik'hamera tsa dijithale, li-microphone le libui, joalo-joalo lekaleng la bareki, li-detectors tsa mocheso, electrocardiographs, litsamaiso tsa lifofane lekaleng la indasteri, lipontšo tse khutlisetsang morao lekaleng la likoloi, jj. Li-analoge chips li fumaneha hohle.

Lipontšo li fetisoa ka mokhoa oa motlakase 'me li arotsoe ka mefuta e' meli ea lipontšo tsa analog, tse fokolang le tse matla, ho itšetlehile ka matla a hona joale / motlakase.Lihlahisoa tsa ketane ea lipontšo li na le boikarabelo ba ho sebetsana le matla a fokolang.Lihlahisoa tsa taolo ea matla li ikarabella haholo bakeng sa ts'ebetso ea matla a matla, empa hape le matla a fokolang.

Sebaka sa 'maraka sa lefats'e sa li-analog chip se ka ba limilione tse likete tse 60 tsa US.Mmaraka oa lefats'e oa lipotoloho tse kopaneng ke USD 340.2 bilione, 'me li-circuits tsa analog li nka 15%.Har'a lipotoloho tsa analog, 'maraka oa ketane ea lipontšo ke $ 14.3 limilione tse likete,' me mmaraka oa taolo ea matla ke $ 21.6 limilione tse likete.Ho qala ka op-amp ea pele e kopaneng e hlahileng ka 1968, ka 2018, lichifi tsa analog e ne e se e le indasteri ea lefats'e ea hoo e ka bang lidolara tse limilione tse likete tse 60.

Hajoale, lik'hamphani tse holimo tsa 10 tsa analog chip li tšoere karolo e fetang halofo ea karolo ea 'maraka.Ka 2018, lik'hamphani tse 10 tse ka sehloohong tsa li-analog chip e ne e le Texas Instruments (TI), Adenor (ADI), Infineon, Skyworks, ST Microelectronics, NXP, Maxim, On Semiconductor, le On Semiconductor.Maxim, On Semi, Microchip, le Renesas.

Har'a bona, Texas Instruments e sebetsa ka ho khetheha tsamaisong ea matla 'me ke moetapele lefapheng lena;ADI e qalile ka li-amplifiers tse sebetsang 'me ke moetapele oa li-converter tsa data, tse nang le karolo e phahameng ea' maraka ho li-op-amps le tsamaiso ea matla.Infineon e ntšitsoe ho Siemens Group mme ke k'hamphani ea semiconductor e thathamisitsoeng e ikemetseng.Likhamphani tsa hajoale tsa maemo a holimo tsa analog chip, tse thehiloeng mathoasong a bo-1960 le lilemong tsa bo-1990 ha li-circuits tse kopaneng li tsoaloa, li holile hammoho le indasteri e kopaneng ea potoloho, ho kenyeletsoa moetapele oa hajoale oa Texas Instruments (1930), moetapele oa mehleng oa National Semiconductor.
