Kev piav qhia dav dav
AD7888 yog ib qho kev kub ceev, qis zog, 12-ntsis ADC uas ua haujlwm los ntawm ib qho 2.7 V rau 5.25 V fais fab mov.AD7888 muaj peev xwm ntawm 125 kSPS throughput tus nqi.Lub tswv yim taug qab-andhold tau txais ib lub teeb liab hauv 500 ns thiab nta ib qho kev ua piv txwv ib zaug.AD7888 muaj yim-kawg analog inputs, AIN1 txog AIN8.Cov tswv yim analog ntawm txhua qhov ntawm cov channel no yog los ntawm 0 rau VREF.Ib feem muaj peev xwm hloov pauv tag nrho lub zog teeb liab mus txog 2.5 MHz.The AD7888 nta ib qho kev siv ntawm 2.5 V uas tuaj yeem siv los ua qhov siv tau rau A / D converter.REF IN / REF OUT tus pin tso cai rau tus neeg siv nkag mus rau qhov kev siv no.Xwb, tus pin no tuaj yeem dhau los muab qhov kev siv hluav taws xob sab nraud rau AD7888.Qhov hluav taws xob ntau rau qhov kev siv sab nraud yog los ntawm 1.2 V rau VDD.CMOS kev tsim kho kom ntseeg tau tias tsis muaj hluav taws xob dissipation ntawm feem ntau 2 mW rau kev ua haujlwm ib txwm muaj thiab 3 µW hauv lub hwj chim-down hom.Cov ib feem muaj nyob rau hauv 16-lead nqaim lub cev me me qhia ( SOIC) thiab 16-lead nyias shrink me txheej txheem (TSSOP) pob.
PRODUCT HIGHLIGHTS
Tsawg tshaj 12-ntsis 8-channel ADC;16-lead TSSOP yog tib thaj chaw raws li 8-lead SOIC thiab tsawg dua li ib nrab ntawm qhov siab.Lowest Fais fab 12-ntsis 8-channel ADC.Siv lub zog tswj kev xaiv suav nrog tsis siv neeg lub hwj chim-down tom qab conversion.Analog input range ntawm 0 V mus rau VREF (VDD).5. Ntau yam serial I / O chaw nres nkoj (SPI / QSPI / MICROWIRE / DSP Tau tshaj).
