Hav guys! Kuv rov los lawm.

Op-amps xav tau ob-polarity mov rau kev ua haujlwm kom raug. Thaum ua haujlwm nrog cov khoom siv roj teeb, nws nyuaj ua kom tau txais lub zog hluav taws xob ob zaug rau op-amps. Tshaj tawm ntawm no yog qhov yooj yim Circuit Court uas muab ± 5V los ntawm roj teeb 9V.

Wb tuaj tos ntawm qhov chaw kuv tawm mus zaum kawg.

Kauj Ruam 1: Tsim Pawg Thawj Coj

Cov duab qhia tau hais tias tsim PCB pawg thawj coj, uas kuv tau txais los ntawm LionCircuits.

Cia peb pib nrog kev sib sau ua ke ntawm pawg tswj hwm no.

Kauj Ruam 2: Cov Rooj Sib Tham Cov Rooj Sib Tham

Cov duab saum toj no qhia tag nrho cov khoom sib dhos ua ke ntawm PCB Board. Kuv tau siv lub roj teeb 9 v rau cov khoom siv nkag. Thaum cov khoom muab rau pawg thawj coj, tus tswj hluav taws xob IC1 hloov 9V roj teeb nkag rau hauv kev tswj 5V. Qhov 5V tso tawm los ntawm IC1 tau muab rau tus pin 8 ntawm IC2. IC2 thiab cov khoom siv hluav taws xob C3 thiab C4 tsim qhov hluav taws xob inverter ntu uas hloov +5V rau -5V. Hloov -5V mov muaj nyob ntawm tus pin 5 ntawm IC2. Hloov pauv ± 5V khoom yog li muaj nyob ntawm txuas CON2.

Kauj Ruam 3: Ntsuas Cov Ntsiab Lus

Ntsuas cov ntsiab lus -> Paub meej

  • TP0 -> +9V
  • TP1 -> +5V
  • TP2 -> 0V (GND)
  • TP3 -> -5V

Saum 3 daim duab qhia pom tau txais qhov sib txawv ntawm qhov tso tawm 3 tus pin txuas, Tshaj tawm ntawm no yog qhov yooj yim Circuit Court uas muab ± 5V los ntawm roj teeb 9V.

Muab nws tso rau hauv lub thawv pov thawj dej. Roj teeb BATT.1 yuav tsum muab ntim rau hauv lub thawv. Txhim kho CON 2 ntawm sab xub ntiag lossis tom qab ntawm lub txee, yog li koj tuaj yeem siv ± 5V yooj yim. Ua ntej siv lub Circuit Court, txheeb xyuas cov qhab nia xeem hauv lub rooj kom ntseeg tau tias ua haujlwm tau zoo ntawm Circuit.
