Ko te putanga he tereina-ki-te-rerewe, a kei roto hoki i nga rerenga kino - ka mahi mai i te 100mV i raro i te raina kino ki te 1.5V i raro i te raina pai.
Ko te ngaohiko nui whakaheke ko te ± 4µV ana, na te ara o te hiko hiko, ka neke noa iho tenei ma te 0.01µV / ° C (te nui ki te 5V) - me te kii a ADI kaore he neke i te waa.
Ko te haruru whakauru he 88nVp-p (0.1Hz ki te 10Hz) me te rahi o te hihiko 4.2nV / √Hz angamaheni i te 1kHz. Ka honoa tenei ki te 168dB angamaheni o te PSRR (te whakakore i te tuku mana, tetahi supply V) me te 160dB CMRR (te paopao aratau noa, -15.1V ki te + 13.5V noa, te tuku 30V).
Ko te taonga ngaohiko tuwhera-tuwhera he 160dB (-14.75Vout ki te + 14.75Vout ki te 10kΩ, 30V supply). Hua hua-whanui ko 5MHz te tikanga.
Tono angamaheni
Koinei te miihini whakaoho-piauau me te ara porowhita ki te pehi i nga oro haruru i te waa tapahi me ona taatai rereke ki raro o te ngaohiko whakaheke. Ko te nui o te riu i te nuinga o te waa tapahi 330kHz, e ai ki te ADI, he iti ake i te 1µVrms.
Kua whakauruhia he aratau kati-iho mo nga tono hiko-iti, ka kati ki
Hei whakaoho-whakararo-whaitake ahakoa te aha o nga raina o te amplifier, he pine 'SDCOM' ki te hono atu ki te papa arorau, muri iho ka riro te pine 'SD' ki te 3V, ki te 5V ranei he whaitake kia hono ki taua pine (arorau '0' mo kati-iho).
Ko nga whiringa kohinga e 8 katoa te mata: SOIC, MSOP ko LFCSP ranei.
He poari aromatawai (whakaahua) e kiia ana ko EVAL-ADA4523-1ARMZ e whakauru ana i tetahi op-amp kua whakauruhia mo te MSOP mo te 101x kore-hurihuri whiwhinga - me te whakawhiwhi i te peahiawhi e taea ana te ~ 39.6kHz. "Ko tenei herenga i roto i te peenewhakaata ka mahi hei taatari iti-paahitanga e paopao ana i nga taonga i hangaia e te 330kHz auau tapahi o roto," e ai ki te ADI. "Ko te whakatakotoranga ka whakaitihia nga awangawanga thermocouple o te takotoranga me nga waahanga e whakauru mai ana i nga ngaohiko takirua nui ake i te ngaohiko mutunga nui."
Ka kitea nga tono i roto i te whanui hihiko: whakamatau, mehua me te whakatangitangi - whiwhinga raraunga, tohutoro tohorite (tirohia te ara iahiko), pauna hiko, whakahiatotanga thermocouple, taumaha taumaha me te taumaha o te waa, hei tauira.
Kei konei te whaarangi hua
I te 2015, i tukuna e ADI te ADA4522, he 4.5 ki te 55V tino iti-nekehanga op-amp e waatea ana i nga waahanga kotahi, takirua me te whaa whaa.
Ka rite ki te pepa raraunga o te ADA4523 hou e whakahua ana i te 'pere amplifier' i etahi wa, he mahere mo te putanga taarua, te tapawhā ranei ADI?
"Ka tukuna pea e maatau he taarua whakarei tapawhā ranei i nga ra kei te heke mai - he mea ka taea. I tenei wa, kotahi noa ta maatau putanga ADA4523-1, "i whakautu a ADI ki a Electronics Weekly.
