♠ INA281-Q1 AEC-Q100, -4-V mpaka 110-V, 1.3-MHz Current-Sense Amplifier
INA281-Q1 ndi amplifier yamakono yolondola kwambiri yomwe imatha kuyeza kutsika kwa magetsi pazitsulo za shunt pamitundu yambiri yofanana kuchokera ku -4 V kufika ku 110 V. Mphamvu yamagetsi yowonongeka imapangitsa kuti chipangizochi chizigwira ntchito pansi, motero kutengera muyeso wolondola wa mafunde obwerezabwereza m'magawo apakati pa mlatho.Kuphatikiza kwa magetsi otsika kwambiri, cholakwika chochepa chopeza ndi DC CMRR yayikulu imathandizira kuyeza kolondola kwambiri.INA281-Q1 sinapangidwe kuti ikhale yoyezera pakali pano ya DC, komanso yogwiritsira ntchito mofulumira kwambiri (monga chitetezo chachangu, mwachitsanzo) ndi bandwidth yapamwamba ya 1.3 MHz ndi 65-dB AC CMRR (pa 50 kHz).
INA281-Q1 imagwira ntchito kuchokera pamtundu umodzi wa 2.7-V mpaka 20-V, kujambula 1.5 mA yamagetsi apano.INA281-Q1 ikupezeka ndi njira zisanu zopindula: 20 V/V, 50 V/V, 100 V/V, 200 V/V, ndi 500 V/V.Zosankha zomwe zapindulazi zimayankhira mitundu ingapo yamapulogalamu omvera.
INA281-Q1 imatchulidwa pa kutentha kwa −40 °C mpaka +125 °C ndipo imaperekedwa mu phukusi la SOT-23 lopulumutsa malo lomwe lili ndi mitundu iwiri ya pini.
