AMC1200SDUBR 100% Tshiab & Original Isolation Amplifier 1 Circuit Differential 8-SOP

Muaj peb txoj hauv kev tsim siv rau kev sib cais amplifiers, suav nrog:

1. Transformer cais

Hom kev rho tawm no siv PWM lossis zaus-modulated signals.Internally, lub amplifier muaj xws li 20 KHz oscillator, rectifier, lim, thiab transformer rau lub hwj chim txhua theem kev sib cais.

1).Lub rectifier yog siv los ua cov tswv yim rau lub tshuab ua haujlwm tseem ceeb.

2).Txuas lub transformer rau lub hwj chim mov.

3).Lub oscillator yog siv los ua cov tswv yim ntawm kev ua haujlwm thib ob amplifier.

4) LPF yog siv los tshem tawm cov khoom ntawm lwm zaus.

5).Qhov zoo ntawm transformer cais feem ntau suav nrog siab CMRR, linearity thiab raug.

Cov ntawv thov rau kev rho tawm transformer suav nrogkho mob, nuclearthiab cov ntawv thov kev lag luam.

2. Optical cais

Hauv qhov kev rho tawm no, lub teeb liab l tuaj yeem hloov pauv los ntawm lub teeb liab lom neeg mus rau qhov pom kev teeb liab los ntawm LED rau kev ua haujlwm ntxiv.Nyob rau hauv cov ntaub ntawv no, tus neeg mob Circuit Court yog input Circuit Court, thaum lub sij hawm tso zis Circuit Court tuaj yeem tsim los ntawm phototransistor.Cov circuits no yog siv los ntawm cov roj teeb.Lub i/p Circuit Court hloov lub teeb liab mus rau hauv lub teeb, thiab lub o/p circuit converts lub teeb rov qab mus rau hauv lub teeb liab.

Qhov zoo ntawm optical cais muaj xws li:

1).Los ntawm kev siv nws, peb tuaj yeem tau txais amplitude thiab raw zaus.

2).Nws txuas nrog optically yam tsis muaj modulator lossis demodulator.

3).Nws txhim kho kev nyab xeeb ntawm tus neeg mob.

Daim ntawv thov ntawm kev sib cais ntawm transformer suav nrog kev tswj cov txheej txheem kev lag luam, kev nrhiav cov ntaub ntawv, kev ntsuas biomedical, kev saib xyuas tus neeg mob, cov khoom sib txuas, cov cuab yeej kuaj, SCR tswj, thiab lwm yam.

3. Capacitor cais tawm

1).Nws siv zaus hloov kho thiab digital encoding ntawm input voltage.

2).Lub input voltage tuaj yeem hloov mus rau tus nqi txheeb ze ntawm qhov hloov pauv capacitor.

3).Nws suav nrog circuits xws li modulator thiab demodulator.

4).Cov teeb liab raug xa los ntawm qhov sib txawv capacitive barriers.

5).Rau ob tog, muab cais.

Qhov zoo ntawm capacitive cais muaj xws li:

1).Qhov kev rho tawm no tuaj yeem siv los tshem tawm cov suab nrov nrov

2).Cov no yog siv los simulate qhov system

3).Nws suav nrog linearity thiab siab nce stability.

4).Nws muaj kev tiv thaiv siab rau cov suab nrov sib nqus

5).Los ntawm kev siv nws, koj tuaj yeem zam lub suab nrov.

Cov ntawv thov rau kev sib cais capacitive suav nrog kev nrhiav cov ntaub ntawv, cov khoom sib txuas, kev saib xyuas tus neeg mob, electroencephalography, thiab electrocardiogram.
