3, Mofuta oa ho hoholeha ha mocheso o tlase
Ka lisebelisoa tse nepahetseng, ho lemoha matšoao a fokolang, le lisebelisoa tse ling tsa ho laola ka mokhoa o itekanetseng, kamehla ho lakatseha hore motlakase oa ho tlosa op-amp o be o monyenyane 'me o se ke oa fetoha le mocheso.Li-amplifiers tse sebetsang tsa mocheso o tlase li etselitsoe morero ona.OP07, OP27, AD508, le ICL7650, sesebelisoa sa chopper-stabilised low-drift se nang le li-MOSFET, ke tse ling tsa li-amplifiers tse sebetsang hantle haholo, tse tlase-tlase tse sebelisoang kajeno.

4, mofuta oa lebelo le phahameng
Ka li-converter tse potlakileng tsa A/D le D/A le li-amplifiers tsa video, sekhahla sa phetoho ea SR ea op-amp e kopaneng e tlameha ho ba holimo mme bandwidth ea phaello ea bonngoe ea BWG e tlameha ho ba kholo ka ho lekana joalo ka sepheo se akaretsang sa op-amps e sa lokelang. dikopo tsa lebelo le phahameng.High-speed op-amps e khetholloa haholo-holo ka litekanyetso tse phahameng tsa phetoho le karabelo e pharaletseng ea maqhubu.Li-op-amps tse tloaelehileng ke LM318, μA715, joalo-joalo, eo SR=50~70V/us, BWG>20MHz.

5,Mofuta o fokolang oa tšebeliso ea matla.
Joalo ka monyetla o moholo oa potoloho ea elektroniki, kopanyo ke ho etsa hore lipotoloho tse rarahaneng li be nyane hape li be bobebe, ka hona, ka ho atolosoa ha mefuta e mengata ea lisebelisoa tse nkehang, hoa hlokahala ho sebelisa phepelo ea motlakase e tlase, tšebeliso e tlase ea matla ea karolo ea ts'ebetso ea amplifier e sebetsang.Li-amplifiers tse sebelisoang ka tloaelo ke TL-022C, TL-060C, joalo-joalo, tseo motlakase oa tsona o sebetsang ± 2V ~ ± 18V, 'me tšebeliso ea hona joale ke 50 ~ 250μA.Lihlahisoa tse ling li fihlile boemong ba μW, mohlala, matla a ICL7600 ke 1.5V, 'me tšebeliso ea matla ke 10mW, e ka tsamaisoang ke betri e le' ngoe.

6, mefuta e phahameng ea motlakase le mefuta e mengata ea matla
Matla a hlahisoang ke li-amplifiers tse sebetsang a fokotsoa haholo ke phepelo ea motlakase.Ho li-amplifiers tse tloaelehileng tsa ts'ebetso, matla a phahameng a hlahisoang hangata ke mashome a 'maloa feela a li-volts mme tlhahiso ea hona joale ke mashome a seng makae a li-milliamp.Ho eketsa motlakase oa tlhahiso kapa ho eketsa tlhahiso ea hona joale, op-amp e kopantsoeng e tlameha ho tlatsoa ka ntle ke potoloho e thusang.Li-voltage tse phahameng le li-op amps tse phahameng tsa hajoale li ka hlahisa motlakase o phahameng le oa hona joale o phahameng ntle le potoloho efe kapa efe e eketsehileng.Mohlala, op-amp e kopaneng ea D41 e ka fana ka li-voltage ho fihla ho ± 150V mme μA791 op-amp e kopaneng e ka tsamaisa maqhubu a tlhahiso ho fihla ho 1A.

7,Mofuta oa taolo o ka lokisoang
Ts'ebetsong ea lisebelisoa, ho na le bothata bo fapaneng.E le hore u fumane tlhahiso e tsitsitseng ea motlakase, ho hlokahala hore u fetole amplifier ea amplifier e sebetsang.Mohlala, amplifier ea ts'ebetso e na le ho holisoa ha makhetlo a 10, ha lets'oao la ho kenya e le 1mv, motlakase o tsoang ke 10mv, ha motlakase o kenang e le 0.1mv, tlhahiso ke 1mv feela, molemong oa ho fumana 10mv, ho holisa ho tlameha ho ba teng. e fetotsoe ho 100. Ka mohlala, PGA103A, ka ho laola boemo ba pin 1,2 ho fetola amplification.
