♠ INA190 Bidirectional, Low-Power, Zero-Drift, Wide Dynamic Range, Precision Current-Sense Amplifier Nokunika amandla
I-INA190 inamandla aphansi, i-voltage-output, i-currentshunt monitor (ebuye ibizwe ngokuthi i-current-sense amplifier). Le divayisi ijwayele ukusetshenziselwa ukuvikela okudlulele, ukulinganisa kwamanje okunembayo ukuze kuthuthukiswe isistimu, noma kumasekhethi empendulo avaliwe. I-INA190 ikwazi ukuzwa ukwehla ku-shunts kuma-voltage emodi evamile ukusuka ku--0.2 V kuye ku-+40 V, ngaphandle kwe-voltage yokuhlinzeka.
Ukuchema okuphansi okokufaka kwamanje kwedivayisi kuvumela ukusetshenziswa kweziphikisayo nomuzwa wamanje omkhulu, ngaleyo ndlela kunikeze izilinganiso zamanje ezinembile kububanzi be-microamp. I-voltage ephansi ye-offset ye-architecture ye-zero-drift inweba ububanzi obuguqukayo besilinganiso samanje. Lesi sici sivumela izinqamuleli zenzwa ezincane ezinokuncipha kwamandla aphansi, kuyilapho sisahlinzeka ngezilinganiso zamanje ezinembile.
I-INA190 isebenza kusuka kokukodwa kokungu-1.7-V kuya kokungu-5.5-V kwamandla kagesi, futhi idonsa umkhawulo ongu-65 µA wokunikezwa kwamandla wamanje uma inikwe amandla; 0.1 µA kuphela uma kukhutshaziwe. Izinketho ezinhlanu zenzuzo engaguquki ziyatholakala: 25 V/V, 50 V/V, 100 V/V, 200 V/V, noma 500 V/V. Idivayisi icaciswe phezu kwebanga lokushisa lokusebenza elingu--40°C kuya ku-+125°C, futhi inikezwa ngamaphakheji e-UQFN, SC70, kanye ne-SOT-23.
