Le amplifier inokuqhuba ngevolthi enye okanye ezimbini ezivela kwi-2.7V ukuya kwi-5.5V, isetyenziselwa kuphela i-7.5mA yomthwalo wombane. Ikhupha i-gain bandwidth product e-90MHz kunye ne-slew rate ye-80V/s, ivumela ukucubungula isiginali okukhawulezayo kunye nobuchule obuphambili bokuphinda-phinda. Le mveliso ixutywe kwi-8-VSSOP (Very Small Outline Package) enesiphelo esincinci sokubeka ngeengxenye zenjini, ikhulula ulwazi lomqambi wokunciphisa indawo kwiinkqubo zombane.
Iimpawu eziphambili ziquka ukugqitywa ngaphandle kobhontsi be-RoHS, ukuzinza okugqwesileyo kwindawo yokushisa, kunye nokusebenza okukhulu kwiinkqubo zolawulo lwemfundo, izixhobo zenyanga, iinkqubo zokunxibelelana nokukhanya, kunye nomphambili wezibane eziyimfuneko ezingaphantsi kobungozi buzothando kunye nokuguqulwa okuphambili kwezinye iindlela zokwenza umsebenzi ophambili.
Iimodeli ezifanayo okanye ezinxibelelanayo ezineempawu ezifana ne-OPA363, i-OPA380, kunye nezinye ii-amplifier ze-transimpedance kwi-portfolio ye-Texas Instruments ye-analog enexabiso liphantsi. Ukunxibelelana kweemodeli nezikhokelo zomqhubi zicwangcisa kakuhle ukunceda abaphandi, abenzi bezixhobo, kunye nabakhi bokuzama be-precision, benza ukuba le mveliso ibe lukhetho oluphambili noluncedo.
I-OPA380AIDGKT imele isisombululo esiphambili kwizicelo ezidinga ukukhutshwa okucothukileyo kwezwi, ukuhambisa okuphezulu kwevolthi, kunye nokuphendula okungcono kwezikhombisi zomphumo yezimo ezahlukeneyo zokusebenza.
