Babban madaidaicin Microvolt/Millivolt ƙarfin lantarki mai ƙaramar siginar kayan aiki amplifier AD620 mai watsawa

Babban madaidaici, ƙarancin rashin daidaituwa, AC, DC microvolt, amplifier ƙarfin lantarki na millivolt, ana iya amfani dashi don AC, ƙaramar siginar ƙaramar siginar, microvolt, ƙarfin ƙarfin lantarki na millivolt. (Amfani da tsarin, kuna buƙatar samun wani tushe na lantarki, idan babu abokin ciniki na asali, da fatan za a saya a hankali, kantin sayar da yana ba da tallafin fasaha.)
Bayanin samfur:
1: Wide shigarwa kewayon Wannan samfurin yana amfani da AD620 amplification, iya karawa microvolt, millivolt, fiye da kasuwa LM358 amplification daidaito ne high, mai kyau linearity, matsakaicin ƙarfin lantarki kewayon fitarwa na ± 10V.
2: Ƙarawa ta amfani da potentiometer don haɓaka siginar shigarwa, haɓakawa har zuwa sau 1000, kawai buƙatar gyara ta hanyar potentiometer.
3: Sifili daidaitacce ta hanyar daidaita sifili potentiometer, inganta daidaito, ba za a sami wani abu mai ɗigo ba, don saduwa da bukatun abokin ciniki.
4: Matsakaicin fitarwa mara kyau yana ɗaukar guntu matsa lamba 7660A don fitar da matsa lamba mara kyau (-Vin), wanda za'a iya ba abokan ciniki don fitar da sauran nau'ikan wutar lantarki biyu.
5: Mini size ne 32 * 22mm, hudu 3mm matsayi ramukan suna a ko'ina rarraba a kusa da, da kuma bangarorin biyu suna jeri tare da 2.54mm misali tazara.
Siffofin samfur:
1. Input ƙarfin lantarki: 3-12VDC. (Za a iya daidaita tsari)
2. Girma: 1.5-1000 sau daidaitacce, sifili daidaitacce
3. Siginar shigar da wutar lantarki: 100uV-300mV
4. Kewayon fitarwa na sigina: ± (Vin-2V)
5. Ƙimar rashin ƙarfi: mafi girma fiye da -Vin. Saboda juriya na ciki na fitarwa na guntu matsa lamba, ainihin fitarwa ya fi girma fiye da -Vin, kuma mafi girman ƙarfin nauyin nauyi, mafi girman raguwar matsa lamba.
6. Rashin wutar lantarki: 50μV.
7. Input bias current: 1.0nA (mafi girman ƙima).
8. Tsarin kin amincewa da yanayin gama gari: 100dB
9. Ƙimar wutar lantarki mai kashewa: 0.6μV / ℃ (mafi girman ƙimar).
10. Tsaya, lokaci: 2μV / Monthmax
11. Module nauyi: 4g
12. Girman: 32*22mm

Yadda ake amfani da:
Lura: +S: shigarwar sigina, -S: shigar da sigina mara kyau (GND ana iya haɗa shi), fitarwar siginar Vout, V- fitarwa a -VIN ƙarfin lantarki (don samar da wutar lantarki). Shigar da sigina, fitarwar sigina, shigar da wutar lantarki, sigina 3 dole ne a raba.

1.Kafin yin amfani da zane na wayoyi, daidaita wayoyi bisa ga zane zuwa sifili, gajeriyar haɗawa + S da -S, daidaita maɓallin sifili don yin fitarwa Vout 0V.

2. Zane-zane na shigar da wayoyi guda ɗaya Wannan zane na wayoyi ya shafi siginonin fitarwa guda ɗaya, na'urori masu auna firikwensin, da ƙwayoyin photovoltaic na silicon.

3.Differential shigarwar zane-zane na wayoyi Wannan zane-zane na wayoyi ya dace da na'urori masu mahimmanci na matsa lamba, Bridges da sauran na'urori masu auna firikwensin.
