O le LT®4430 e fa'auluina le opto-coupler e laasia le pa u'amea i totonu o se sapalai eletise tu'ufua.O le IC o loʻo i ai
o se faʻamatalaga saʻo-faʻapipiʻiina, o se mea sese maualuga bandwidth
fa'aola, o se fa'aliliuina o le 6 tulaga e fa'aulu ai le optocoupler ma tulaga tulaga ese overshoot pulea circuitry.
O le LT4430's 600mV fa'asinomaga maua ± 0.75% muamua
saʻo ma ± 1.25% faapalepale i luga o le vevela.A maualuga
bandwidth 9MHz fa'ase'e fa'amalo fa'ataga faigofie fa'avave
taui ma suiga fa'atama'i la'asaga ile fa'aoga masani
laina fa'alava.O le avetaavale opto-coupler e maua
10mA o le gaosiga o loʻo i ai nei ma o loʻo puipuia pupuu.
O se galuega fa'atonutonu fa'ato'a fa'apitoa e taofia ai le gaosiga
overshoot i luga o le amataga ma le toe faaleleia o le li'o pu'upu'u ma a
tasi capacitor.
O lo'o maua le LT4430 ile fa'ailoga maualalo 6-lead TSOT-23
