AD7760BSVZ IC ADC 24BIT SIGMA-DELTA 64TQFP

Kev piav qhia

AD7760 yog qhov ua tau zoo, 24-ntsis Σ-Δ analog-rau-digital converter (ADC).Nws muab cov tswv yim dav bandwidth thiab kev kub ceev nrog cov txiaj ntsig ntawm Σ-Δ hloov dua siab tshiab kom ua tiav qhov kev ua tau zoo ntawm 100 dB SNR ntawm 2.5 MSPS, ua rau nws zoo tagnrho rau kev ceev cov ntaub ntawv tau txais.Dav dynamic ntau ua ke nrog txo cov kev cai antialiasing kom yooj yim rau cov txheej txheem tsim.Ib qho kev tsis sib xyaw ua ke los tsav cov kev siv, qhov sib txawv amplifier rau cov teeb liab buffering thiab qib hloov, tus chij overrange, kev nce hauv thiab offset sau npe, thiab qis-dhau digital FIR lim ua rau AD7760 ib qho kev sib cog lus, sib koom ua ke cov ntaub ntawv tau txais cov cuab yeej xav tau tsawg kawg nkaus peripheral kev xaiv cov khoom.Tsis tas li ntawd, cov cuab yeej muaj qhov programmable decimation tus nqi, thiab cov lim FIR digital tuaj yeem hloov kho yog tias cov yam ntxwv tsis tsim nyog rau daim ntawv thov.AD7760 yog qhov zoo tagnrho rau cov ntawv thov uas xav tau siab SNR yam tsis muaj teeb meem ua ntej-kawg tsim.Cov tswv yim sib txawv yog ua piv txwv txog li 40 MSPS los ntawm ib qho analog modulator.Lub modulator tso zis yog ua tiav los ntawm ib tug series ntawm lowpass lim, nrog rau qhov kawg lim muaj default los yog user-programmable coefficients.Tus nqi piv txwv, lim kaum zaus, thiab cov lus tso tawm tus nqi raug teeb tsa los ntawm kev sib xyaw ntawm cov moos sab nraud thiab cov ntawv teev npe ntawm AD7760.Qhov kev siv hluav taws xob xa mus rau AD7760 txiav txim siab qhov sib txawv ntawm cov tswv yim.Nrog rau 4 V siv, qhov analog input range yog ± 3.2 V qhov sib txawv ntawm qhov sib txawv ntawm 2 V. Qhov kev sib txawv hom kev sib txawv no tuaj yeem ua tiav siv cov on-chip sib txawv amplifier, ntxiv txo cov teeb liab sab nraud.Lub AD7760 muaj nyob rau hauv qhov nthuav dav paddle, 64-lead TQFP thiab tau teev dhau qhov kev lag luam kub ntawm -40 ° C txog + 85 ° C.
