♠ INA281-Q1 AEC-Q100, -4-V rau 110-V, 1.3-MHz Tam sim no-Sense Amplifier

Lub INA281-Q1 yog lub siab-precision tam sim no amplifier uas tuaj yeem ntsuas qhov hluav taws xob poob thoob plaws shunt resistors tshaj qhov ntau hom hom ntawm -4 V rau 110 V. Qhov tsis zoo-hom voltage tso cai rau cov cuab yeej ua haujlwm hauv qab av, yog li ua raws li kev ntsuas qhov tseeb ntawm cov khoom siv rov ua dua tshiab hauv kev siv ib nrab choj.Kev sib xyaw ua ke ntawm qhov tsis tshua muaj hluav taws xob tsawg, qhov nce me me yuam kev thiab siab DC CMRR ua rau qhov ntsuas tam sim no muaj tseeb.INA281-Q1 tsis yog tsuas yog tsim los rau DC tam sim no ntsuas, tab sis kuj rau kev siv high-ceev (xws li kev tiv thaiv overcurrent ceev, piv txwv li) nrog lub siab bandwidth ntawm 1.3 MHz thiab 65-dB AC CMRR (ntawm 50 kHz).

INA281-Q1 ua haujlwm los ntawm ib qho 2.7-V rau 20-V muab, kos 1.5 mA ntawm cov khoom tam sim no.INA281-Q1 muaj nyob nrog tsib txoj kev nce qib: 20 V / V, 50 V / V, 100 V / V, 200 V / V, thiab 500 V / V.Cov kev xaiv tau txais no nyob rau ntau qhov kev hloov pauv rau cov ntawv thov tam sim no.

INA281-Q1 tau teev dhau qhov kev ua haujlwm kub ntawm -40 ° C rau + 125 ° C thiab muaj nyob rau hauv qhov chaw txuag SOT-23 pob nrog ob tus pin-tawm variants.
