SI 8921 BD-IS4R

SI8921BD-IS4R yog ntau yam kev sib cais amplifier nrog cov yam ntxwv zoo. Nws muaj cov kev xaiv qis-voltage sib txawv ntawm ± 62.5 mV thiab ± 250 mV, tsis tshua muaj teeb liab ncua (0.8 μs), thiab zoo heev precision nrog ib tug raug input offset ntawm ±{{11} }.40 μV thiab raug yuam kev ntawm ±0.06%. Qhov no amplifier ua tau zoo hauv kev tswj xyuas qhov tseeb txawm tias nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, nrog rau kev sib tw ntawm 0.5 μV / degree thiab ib txwm nce drift ntawm -9 ppm / degree . Nws muaj qis nonlinearity (0.003% tag nrho-teev), lub teeb liab-rau-suab nrov piv (82 dB), thiab qis tag nrho kev sib haum xeeb distortion (-88 dB). Tsis tas li ntawd, nws muaj kev tiv thaiv kev tiv thaiv ib puag ncig siab ntawm 75 kV / μs thiab kev xaiv tsheb-qib nrog AEC-Q100 kev tsim nyog thiab kev txhawb nqa cov ntaub ntawv. Nrog cov pob khoom sib txuas thiab kev ua haujlwm kub ntawm -40 txog 125 degree, SI8921BD-IS4R yog cov kev ua haujlwm siab tsim nyog rau ntau yam kev siv.

• Muaj, HEV thiab lub zog tauj dua tshiab inverters

• AC, brushless, thiab DC lub cev muaj zog tswj thiab tsav

• Kev tswj lub cev muaj zog sib txawv hauv cov khoom siv dawb

• Kev rho tawm hom hloov thiab UPS cov khoom siv hluav taws xob

• Automotive on-board chargers, roj teeb tswj systems, thiab them chaw nres tsheb

Lub Si8921 thiab Si8922 galvanically cais cov analog amplifiers muaj cov khoom siv hluav taws xob tsawg tsawg, zoo tagnrho rau kev ntsuas qhov hluav taws xob hla lub tam sim no shunt resistor lossis txhua qhov chaw uas lub sensor yuav tsum raug cais tawm ntawm qhov kev tswj hwm. Cov zis yog qhov sib txawv analog teeb liab amplified los ntawm 8.2x lossis 32.8x.

Lub teeb liab qeeb qeeb ntawm Si8921/22 tso cai rau cov tshuab tswj kom teb sai sai rau cov xwm txheej tsis raug lossis hloov pauv hauv kev thauj khoom. Tsawg offset thiab nce drift kom ntseeg tau tias qhov tseeb yog tswj hwm tag nrho cov kev khiav hauj lwm kub. Tshwj xeeb tshaj yog hom kev tiv thaiv ib puag ncig zoo txhais tau hais tias Si8921/22 muab cov kev ntsuas raug tseeb txawm tias muaj kev hloov pauv hluav taws xob ntau raws li pom hauv lub cev muaj zog thiab cov inverter.

Lub Si8921/22 cais voltage sensing amplifier siv Skyworks proprietary rho tawm technology, thiab tiv taus mus txog 5.0 kVRMS ib UL1577. Cov thev naus laus zis no ua rau muaj kev ua haujlwm siab, txo qhov sib txawv ntawm qhov kub thiab qhov muaj hnub nyoog, nruj dua ib feem ntawm qhov sib txuam, thiab lub neej ntev dua piv rau lwm cov thev naus laus zis. Automotive Qib muaj rau qee tus lej. Cov khoom no yog tsim los siv cov tsheb tshwj xeeb ntws ntawm txhua kauj ruam hauv cov txheej txheem tsim khoom kom ntseeg tau tias qhov muaj zog thiab qhov tsis zoo uas yuav tsum tau siv rau kev siv tsheb.
