Zotsatira zake ndi njanji yanjanji, ndipo zolowetsazo zimaphatikizapo njanji yoyipa - yogwira kuchokera ku 100mV pansi pa njanji yoyipa mpaka 1.5V pansi pa njanji yabwino.
Kutulutsa kocheperako kumakhala ± 4 andV ndipo, chifukwa chodziyesa nokha, izi zimangoyenda pa 0.01µV / ° C (max pa 5V) - ndipo ADI imati zero zimayenda pakapita nthawi.
Phokoso lolowera nthawi zambiri limakhala 88nVp-p (0.1Hz mpaka 10Hz) lokhala ndi mawonekedwe a 4.2nV / √Hz ofanana ndi 1kHz. Izi zikuphatikizidwa ndi 168dB yodziwika PSRR (kukana magetsi, magetsi aliwonse V) ndi 160dB CMRR (kukana wamba, -15.1V mpaka + 13.5V wamba, 30V kotengera).
Kutseguka kwama voliyumu otseguka nthawi zambiri kumakhala 160dB (-14.75Vout to + 14.75Vout into 10kΩ, 30V supply). Zopindulitsa-bandwidth nthawi zambiri zimakhala 5MHz.
Chitsanzo ntchito
Ichi ndi chopukusira chokhazikika chomwe chimakhala ndi chopukutira chopondereza matani osagwira pafupipafupi komanso ma harmoniki ake osamvetseka mpaka kutsika kwama voliyumu. Kukula kwamphamvu pakachepetsa 330kHz, malinga ndi ADI, ndi ochepera 1µVrms.
Njira yotsekera imaphatikizidwa ndi kugwiritsa ntchito mphamvu zochepa, kutseka mpaka
Kupanga kutseka kwamalingaliro mosagwirizana ndi njanji yama amplifier, pali pini ya 'SDCOM' yolumikizira kumalo amtundu, pambuyo pake pini ya 'SD' imakhala 3V kapena 5V logic yolingana ndi pini (logic '0' ya Tsekani).
Zosankha phukusi ndizotsogolera zonse za 8: SOIC, MSOP kapena LFCSP.
Pali bolodi lowunikira (yojambulidwa) lotchedwa EVAL-ADA4523-1ARMZ yomwe imaphatikizapo pulogalamu ya MS-op op-amp yolumikizidwa ndi phindu la 101x losasunthika - yopereka chiwongolero chothandiza cha ~ 39.6kHz. "Kuchepetsa uku kwa bandwidth kumakhala ngati fyuluta yotsika yomwe imakana zojambula zomwe zimapangidwa ndi 330kHz mafupipafupi odula mkati," malinga ndi ADI. "Kapangidwe amachepetsa mphamvu thermocouple wa kufufuza ndi zigawo zikuluzikulu zomwe zimayambitsa voltages voliyumu kuposa voteji pazipita kuchepetsa."
Mapulogalamuwa akuwonetsedweratu pamitundu yayikulu yamphamvu: kuyesa, kuyeza ndi kugwiritsa ntchito zida - kupeza deta, kugwiritsira ntchito kutanthauzira (onani dera), masikelo amagetsi, ma amplifiers a thermocouple, ma amplifiers a gauge amplifiers komanso malingaliro apansi, mwachitsanzo.
Tsamba lazogulitsa lili pano
Mu 2015, ADI idatulutsa ADA4522, 4.5 mpaka 55V mwatsatanetsatane otsika-op op amp amp amp, omwe amapezeka m'mitundu imodzi, iwiri ndi quad.
Monga momwe pepala la data la ADA4523 yatsopano limatchulira 'pa amplifier' kangapo, mapulani aliwonse a ADI apawiri kapena a quad?
"Titha kutulutsa zida ziwiri kapena zinayi mtsogolo - ndizotheka. Kuyambira pano, tili ndi mtundu umodzi wokha womwe ndi ADA4523-1, ”adatero ADI ku Electronics Weekly.
