Ukunemba okuphezulu kwe-Microvolt/Millivolt voltage amplifier Isikhulisi sesandisi sensimbi Esincane Esisignali se-AD620

Ukunemba okuphezulu, ukungalingani okuphansi, i-AC, i-DC microvolt, i-millivolt voltage amplifier, ingasetshenziselwa i-AC, i-DC yokukhulisa isignali encane, i-microvolt, i-millivolt voltage amplification.(Ukusetshenziswa kwemojula, udinga ukuba nesisekelo esithile se-elekthronikhi, uma lingekho ikhasimende eliyisisekelo, sicela uthenge ngokucophelela, isitolo sinikeza ukwesekwa kwezobuchwepheshe.)
Izithombe ezinhle kakhulu zomkhiqizo:
1: Ibanga lokufakwayo elibanzi Lo mkhiqizo usebenzisa i-AD620 amplification, ingakhulisa i-microvolt, i-millivolt, kunemakethe yokunemba kokukhulisa i-LM358 iphezulu, i-linearity enhle, ububanzi bokukhishwa kwamandla kagesi obuphezulu obungu-±10V.
2: Ukukhulisa usebenzisa i-potentiometer ukukhulisa isignali yokufaka, ukukhulisa izikhathi ezifika ku-1000, kudinga ukulungiswa kuphela nge-potentiometer.
3: Uziro olungisekayo ngokulungisa i-zero potentiometer, uthuthukise ukunemba, ngeke kube khona i-zero drift phenomenon, ukuhlangabezana nezidingo zamakhasimende.
I-4: Imodyuli yokukhishwa kwengcindezi engalungile ithatha i-7660A i-chip ye-pressure negative ukuze ikhiphe ingcindezi engalungile (-Vin), enganikezwa amakhasimende ukushayela eminye imithwalo yamandla amabili.
5: Usayizi omncane ungu-32*22mm, izimbobo ezine zokubeka ezingu-3mm zisakazwa ngokulinganayo nxazonke, futhi izinhlangothi zombili zikleliswe ngesikhala esijwayelekile esingu-2.54mm.
Amapharamitha womkhiqizo:
1. I-voltage yokufaka: 3-12VDC.(Iqoqo lingenziwa ngezifiso)
2. Ukukhulisa: 1.5-1000 izikhathi adjustable, zero adjustable
3. I-voltage yokufaka isignali: 100uV–300mV
4. Ibanga lokuphumayo lesiginali: ± (Vin-2V)
5. Ukukhishwa kwengcindezi engalungile: kukhulu kune -Vin.Ngenxa yokumelana kwangaphakathi kokuphuma kwe-chip ye-pressure negative, okukhiphayo kwangempela kukhulu kune-Vin, futhi amandla amakhulu okulayisha, ukwehla okukhulu kwengcindezi embi.
6. I-Offset voltage: 50μV.
7. Yamanje yokuchema kokokufaka: 1.0nA (inani eliphezulu).
8. Isilinganiso sokwenqatshwa kwemodi evamile: 100dB
9. I-offset voltage drift: 0.6μV/℃ (inani eliphezulu).
10. Izinzile, isikhathi: 2μV/ Monthmax
11. Isisindo semojuli: 4g
12. Usayizi: 32 * 22mm

Isetshenziswa kanjani:
Qaphela: +S: okokufaka kwesignali, -S: isignali yokufaka igethivu (i-GND ingaxhunywa), ukuphuma kwesignali ye-Vout, i-V- output a -VIN voltage (for sensor power supply).Okokufaka kwesignali, ukuphuma kwesignali, okokufaka kwamandla, amasignali ama-3 kufanele kwabelwane ngawo.

1.Ngaphambi kokusebenzisa umdwebo wokufaka izintambo, lungisa izintambo ngokomdwebo uye ku-zero, xhuma i-short-connect +S kanye -S, lungisa i-knob enguziro ukuze wenze ukuphuma kwe-Vout 0V.

2.Umdwebo wezintambo wokufakwayo onesiphetho esisodwa Lo mdwebo wezintambo usebenza kumasignali okukhiphayo anesiphetho esisodwa, izinzwa, namaseli e-silicon photovoltaic.

3.I-Differential input wiring diagram Lo mdwebo wezintambo ulungele izinzwa zokucindezela okukhiphayo okuhlukile, Amabhuloho nezinye izinzwa.
