Kev piav qhia
AD9251 yog monolithic, dual-channel, 1.8 V mov, 14-ntsis, 20 MSPS / 40 MSPS / 65 MSPS / 80 MSPS analog-to-digital converter (ADC).Nws nta cov qauv kev ua haujlwm siab-andhold circuit thiab on-chip voltage siv.Cov khoom siv multistage sib txawv pipeline architecture nrog tso zis yuam kev kho logic muab 14-ntsis raug ntawm 80 MSPS cov ntaub ntawv tus nqi thiab lav tsis muaj cov lej ploj dhau qhov kev ua haujlwm kub tag nrho.ADC muaj ntau yam qauv tsim los ua kom yooj yim thiab txo tus nqi ntawm cov kab ke, xws li lub moos programmable thiab cov ntaub ntawv sib dhos thiab programmable digital test qauv tsim.Cov qauv kuaj digital muaj xws li kev txiav txim siab thiab cov qauv pseudorandom, nrog rau cov qauv kev ntsuas tus neeg siv kev cai nkag los ntawm qhov chaw nres nkoj serial interface (SPI).Lub moos sib txawv ntawm cov tswv yim tswj txhua qhov kev hloov pauv sab hauv.Ib qho kev xaiv lub luag haujlwm lub voj voog stabilizer (DCS) them nyiaj rau ntau qhov sib txawv hauv lub voj voog lub luag haujlwm thaum tswj hwm ADC kev ua tau zoo tag nrho.Cov ntaub ntawv tso tawm digital yog nthuav tawm hauv offset binary, grey code, lossis ob hom ntawv ntxiv.Lub moos tso zis cov ntaub ntawv (DCO) yog muab rau txhua qhov ADC channel los xyuas kom meej lub sijhawm latch kom zoo nrog kev txais cov logic.Ob leeg 1.8 V thiab 3.3 V CMOS qib tau txais kev txhawb nqa thiab cov ntaub ntawv tso tawm tuaj yeem muab faib ua ntau yam rau ib lub tsheb npav nkaus xwb.AD9251 muaj nyob rau hauv 64-lead RoHS Raws Li LFCSP thiab tau teev dhau qhov ntsuas kub ntawm kev lag luam (-40 ° C txog +85 ° C).
