Saxeexa sare ee Microvolt/Millivolt cod-weyneeye korantada yar-yar ee qalabka cod-weyneeye AD620

Saxnaanta sare, dheelitir la'aanta hooseeya, AC, microvolt DC, amplifier danab millivolt, waxaa loo isticmaali karaa AC, cod-weyneeynta signal yar ee DC, microvolt, millivolt kor u qaadida. (Isticmaalka moduleka, waxaad u baahan tahay inaad yeelato aasaas elektaroonig ah, haddii aysan jirin macaamiil aasaasi ah, fadlan si taxadar leh u iibso, dukaanku wuxuu bixiyaa taageero farsamo.)
Waxyaabaha ugu muhiimsan:
1: Kala duwanaanta wax-soo-saarka ballaaran Alaabtani waxay isticmaashaa xoojinta AD620, waxay kordhin kartaa microvolt, millivolt, marka loo eego suuqa LM358 saxnaanta kor u kaca waa mid sarreeya, khad wanaagsan, xajmiga ugu sarreeya ee wax soo saarka ± 10V.
2: Kordhinta iyadoo la adeegsanayo potentiometer si kor loogu qaado calaamadda gelinta, kordhinta ilaa 1000 jeer, kaliya waxay u baahan tahay in lagu hagaajiyo iyada oo loo marayo potentiometer.
3: eber la hagaajin karo iyadoo la hagaajinayo potentiometer eber, hagaajinta saxnaanta, ma jiri doonto wax ifafaale eber ah, si loo daboolo baahiyaha macaamiisha.
4: Qalabka wax soo saarka cadaadiska taban wuxuu qaataa 7660A chip cadaadis taban si uu u soo saaro cadaadiska taban (-Vin), kaas oo la siin karo macaamiisha si ay u kaxeeyaan culeysyo kale oo laba geesood ah.
5: Cabbirka yar waa 32 * 22mm, afar godadka meelaynta 3mm ayaa si siman loo qaybiyey, labada dhinacna waxaa lagu safay 2.54mm fogaan caadi ah.
Qiyaasaha badeecada:
1. Voltage Input: 3-12VDC. ( Dufcaddii waa la beddeli karaa)
2. Weyneynta: 1.5-1000 jeer la hagaajin karo, eber la hagaajin karo
3. Korontada gelinta signalka: 100uV-300mV
4. Kala duwanaanshaha soosaarka isha: ± (Vin-2V)
5. Wax soo saarka cadaadiska xun: ka weyn -Vin. Sababtoo ah iska caabbinta gudaha ee wax-soo-saarka jajabka cadaadiska taban, wax-soo-saarka dhabta ah wuxuu ka weyn yahay -Vin, iyo awoodda culeyska weyn, way sii weyn tahay hoos u dhaca cadaadiska xun.
6. Danab ka-baxsan: 50μV.
7. Gelitaanka eexda hadda: 1.0nA (qiimaha ugu sarreeya).
8. Saamiga diidmada habka caadiga ah: 100dB
9. Daboolista korantada: 0.6μV/℃ (qiimaha ugu sarreeya).
10. Joogto, wakhtiga: 2μV/ Monthmax
11. Culayska Module: 4g
12. Cabbirka: 32*22mm

Sida loo isticmaalo:
Fiiro gaar ah: +S: gelinta signalka, -S: signal-ku-gelinta taban (GND waa lagu xidhi karaa), soo saarista signalka Vout, V-out a -VIN danab (loogu talagalay sahayda tamarta dareemayaasha). Gelitaanka ishaarada, soo saarista ishaarada, galinta awooda, 3 calaamadood waa in la wadaago.

1.Kahor intaadan isticmaalin jaantuska xargaha, ku hagaaji fiilooyinka si waafaqsan jaantuska ilaa eber, isku xir gaaban +S iyo -S, hagaajin buro eber si aad u sameyso wax soo saarka Vout 0V.

2.Jaantuska fiilooyinka wax-gelinta hal-dhammaadka ah Jaantuska fiilooyinka waxa uu khuseeyaa calaamadaha wax-soo-saarka ee hal-dhamaadka ah, dareemayaasha, iyo unugyada sawir-qaadista ee silicon.

3.Jaantuska fiilooyinka wax-soo-saarka ee kala duwan Jaantuskan xargaha ayaa ku habboon dareemayaasha cadaadiska wax-soo-saarka ee kala duwan, Buundooyinka iyo dareemayaasha kale.
