Chithunzi cha ROHM BD7280YG-Ctage Follower Low Noise ndi Input-output Rail-to-Rail High Speed ​​​​CMOS Operational AmpLifier kwa Automotive User Guide

Derali limatengera kuyankha pafupipafupi ndi Op-Amp ngati voltagndi otsatira. Mutha kuwona kupindula kwa AC ndi gawo la kuchuluka kwa zotulutsa ndi voliyumu yoloweratage pamene gwero lolowera voltage AC pafupipafupi imasinthidwa. Mutha kusintha magawo azinthu zomwe zikuwonetsedwa mubuluu, monga VSOURCE, kapena zotumphukira, ndikutsanzira vol.tage wotsatira ali ndi chikhalidwe chomwe akufuna. Mutha kutsanzira dera muzolemba zosindikizidwa: Zogwira ntchito ampLifier, Comparator (Tutorial). [JP] [EN] [CN] [KR]

Machenjezo Azambiri

Chenjezo 1: Miyezo kuchokera muzotsatira zofananira sizotsimikizika. Chonde gwiritsani ntchito zotsatira izi ngati kalozera wamapangidwe anu.
Chenjezo 2: Makhalidwe awa ali pa Ta=25°C. Chifukwa chake, zotsatira zofananira ndi kusiyanasiyana kwa kutentha zitha kusiyana kwambiri ndi zomwe zachitika pa bolodi lenileni (muyeso weniweni).
Chenjezo 3: Chonde onani zolemba za Op-Amps kuti mudziwe zambiri zaukadaulo.
Chenjezo 4: Makhalidwe amatha kusintha kutengera kapangidwe ka bolodi lenileni ndipo ROHM imalimbikitsa mwamphamvu kuti muyang'anenso mawonekedwewo ndi bolodi lenileni pomwe tchipisi tiyimitsidwa.

Simulation Schematic

Momwe mungatsanzirire

Zokonda zofananira, monga kusesa kwa parameter kapena kuphatikizika, zimatha kusinthidwa kuchokera pa 'Simulation Settings' yomwe ikuwonetsedwa pa chithunzi 2, ndipo Gulu 1 likuwonetsa kukhazikitsidwa kosasintha kwa kayesedwe. Pankhani ya convergence yoyeserera, mutha kusintha zosankha zapamwamba kuti muthetse. Kutentha kumayikidwa ku 27 ° C m'mawu okhazikika mu 'Zosankha Pamanja'. Mutha kusintha.
