High Precision Microvolt/Millivolt voltage amplifier Small Signal instrumentation amplifier AD620 transmitter

Ho nepahala ho phahameng, ho se leka-lekane ho fokolang, AC, DC microvolt, millivolt voltage amplifier, e ka sebelisoa bakeng sa AC, DC e matlafatsang pontšo e nyenyane, microvolt, millivolt voltage amplification. (Tšebeliso ea mojule, o hloka ho ba le motheo o itseng oa elektroniki, haeba ho se na moreki oa mantlha, ka kopo reka ka hloko, lebenkele le fana ka tšehetso ea tekheniki.)
Lintlha-khōlō tsa sehlahisoa:
1: Mefuta e mengata ea ho kenya lihlahisoa Sehlahisoa sena se sebelisa AD620 amplification, se ka matlafatsa microvolt, millivolt, ho feta 'maraka LM358 amplification ho nepahala ho phahameng, linearity e ntle, tekanyo e phahameng ea tlhahiso ea motlakase ea ± 10V.
2: Ho phahamisa ho sebelisa potentiometer ho holisa lets'oao la ho kenya, ho holisa ho fihlela makhetlo a 1000, ho hlokahala feela ho lokisoa ka potentiometer.
3: Zero e fetolehang ka ho lokisa zero potentiometer, ntlafatsa ho nepahala, ho ke ke ha e-ba le ketsahalo ea zero drift, ho finyella litlhoko tsa bareki.
4: Mojule oa khatello e mpe ea khatello e amohela 7660A khatello e mpe ea chip ho hlahisa khatello e mpe (-Vin), e ka fuoang bareki ho khanna meroalo e meng ea matla a mabeli.
5: Boholo bo bonyenyane ke 32 * 22mm, masoba a mane a 3mm a ajoa ka ho lekana, 'me mahlakore a mabeli a hlophisitsoe ka sebaka se tloaelehileng sa 2.54mm.
Lintlha tsa sehlahisoa:
1. Matla a kenyang: 3-12VDC. (Batch e ka etsoa ka mokhoa o ikhethileng)
2. Ho hōlisa: 1.5-1000 makhetlo a fetohang, zero e ka fetoha
3. Motlakase oa ho kenya pontšo: 100uV-300mV
4. Lethathamo la tlhahiso ea matšoao: ± (Vin-2V)
5. Khatello e mpe ea khatello: e kholo ho feta -Vin. Ka lebaka la ho hanyetsa ka hare ho tlhahiso ea khatello e mpe ea chip, tlhahiso ea sebele e kholo ho feta -Vin, 'me matla a mangata a mojaro, a theoha haholo khatello e mpe.
6. Offset voltage: 50μV.
7. Kenyelletso ea hona joale: 1.0nA (boleng bo ka holimo).
8. Karolelano ea ho hana mokhoa o tloaelehileng: 100dB
9. Offset voltage drift: 0.6μV/℃ (boleng bo ka holimo).
10. E tsitsitseng, nako: 2μV/ Monthmax
11. Boima ba module: 4g
12. Boholo: 32 * 22mm

Mokhoa oa ho sebelisa:
Tlhokomeliso: +S: ho kenya lets'oao, -S: lets'oao le fosahetseng (GND e ka kopanngoa), Phallo ea pontšo ea Vout, V- output a -VIN voltage (bakeng sa phepelo ea motlakase oa sensor). Kenyelletso ea mats'oao, tlhahiso ea lets'oao, ho kenya matla, matšoao a 3 a tlameha ho arolelanoa.

1.Pele u sebelisa setšoantšo sa wiring, lokisa mohala ho ea ka setšoantšo ho zero, short-connect + S le -S, lokisa lesela la zero ho etsa tlhahiso ea Vout 0V.

2.Sets'oants'o sa wiring se nang le pheletso e le 'ngoe Sets'oants'o sena sa wiring se sebetsa ho mats'oao a tlhahiso a pheletso e le 'ngoe, li-sensor, le lisele tsa silicon photovoltaic.
