Ukuchaneka okuphezulu kwe-Microvolt / i-Millivolt iamplifier yamandla ombane amancinci Uphawu oluncinci lwesixhobo sokwenza iamplifier AD620 isidluliseli

Ukuchaneka okuphezulu, ukungalingani okuphantsi, i-AC, i-DC microvolt, i-millivolt voltage amplifier, ingasetyenziselwa i-AC, i-DC encinci ye-amplification yesignali, i-microvolt, i-millivolt voltage amplification. (Ukusetyenziswa kwemodyuli, kufuneka ube nesiseko esithile sombane, ukuba akukho mthengi osisiseko, nceda uthenge ngokucophelela, ivenkile inikeza inkxaso yobugcisa.)
Amagqabantshintshi emveliso:
I-1: Uluhlu olubanzi lwegalelo Le mveliso isebenzisa i-AD620 yokukhulisa, inokukhulisa i-microvolt, i-millivolt, kunemarike ye-LM358 ukuchaneka kwe-amplification iphezulu, i-linearity elungileyo, ubuninzi be-voltage output range ye-±10V.
I-2: Ukukhulisa usebenzisa i-potentiometer ukukhulisa isignali yokufaka, ukukhulisa ukuya kumaxesha angama-1000, kufuneka kuphela ukulungiswa nge-potentiometer.
I-3: Ukulungiswa kwe-zero ngokulungelelanisa i-potentiometer ye-zero, ukuphucula ukuchaneka, akuyi kuba ne-zero drift phenomenon, ukuhlangabezana neemfuno zabathengi.
I-4: Imodyuli yemveliso yoxinzelelo olubi ithatha i-7660A i-chip yoxinzelelo olubi kwimveliso yoxinzelelo olubi (-Vin), olunokuthi lunikezelwe kubathengi ukuba baqhube enye imithwalo yamandla amabini.
I-5: Ubungakanani obuncinci buyi-32 * 22mm, imingxuma emine ye-3mm yokumisa ihanjiswa ngokulinganayo ngeenxa zonke, kwaye amacala amabini ahlanganiswe kunye ne-2.54mm yezithuba eziqhelekileyo.
Imilinganiselo yemveliso:
1. Igalelo lombane: 3-12VDC. (Iqela linokwenziwa ngokwezifiso)
2. Ukwandiswa: amaxesha e-1.5-1000 ahlengahlengiswayo, i-zero iguquguqukayo
3. Umbane wegalelo lomqondiso: 100uV–300mV
4. Uluhlu lwemveliso yomqondiso: ± (Vin-2V)
5. Imveliso yoxinzelelo olubi: inkulu kune -Vin. Ngenxa yokuchasana kwangaphakathi kwemveliso ye-chip ye-negative chip, imveliso yangempela inkulu kune-Vin, kwaye amandla amakhulu omthwalo, ukwehla koxinzelelo olubi.
6. I-Offset voltage: 50μV.
7. I-Input bias current: 1.0nA (ixabiso eliphezulu).
8. Umlinganiselo wokulahlwa kwendlela eqhelekileyo: 100dB
9. I-Offset voltage drift: 0.6μV/℃ (ixabiso eliphezulu).
10. Ukuzinza, ixesha: 2μV / Monthmax
11. Ubunzima bemodyuli: 4g
12. Ubungakanani: 32 * 22mm

Kusetyenziswa kwanjani:
Qaphela: +S: igalelo lomqondiso, -S: igalelo lesignali elibi (i-GND inokudityaniswa), imveliso ye-Vout ye-Vout, i-V-output ye-VIN yombane (ye-sensor power supply). Ukufakwa kwesignali, ukuphuma kwesignali, igalelo lamandla, iimpawu ezi-3 kufuneka zabiwe.

1.Ngaphambi kokusebenzisa umzobo we-wiring, lungisa i-wiring ngokomzobo ukuya kwi-zero, i-short-connect + S kunye -S, lungisa iqhosha le-zero ukwenza i-Vout 0V ephumayo.

2.Umzobo we-wiring ye-single-ended Single-ended Diagram ye-wiring isebenza kwi-single-end output signals, i-sensor, kunye neeseli ze-silicon photovoltaic.

3.I-Differential input wiring diagram Lo mzobo we-wiring ufanelekile kwi-differential output sensors pressure, iiBridges kunye nezinye izinzwa.
