♠ 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 madontho amagetsi pazitsulo za shunt pamitundu yambiri yofanana kuchokera ku -4 V mpaka 110 V. Zowonongeka zowonongeka zimalola kuti chipangizochi chizigwira ntchito pansi pa nthaka, motero kulandira kuyeza kolondola kwa mafunde obwerezabwereza mu mapulogalamu a theka la 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 ntchito zothamanga kwambiri (monga chitetezo chothamanga kwambiri, 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 yosiyanasiyana 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.
