INGCACISO NGOKUBANZI
I-AD7888 isantya esiphezulu, amandla aphantsi, i-12-bit ADC esebenza ukusuka kwi-2.7 V eyodwa ukuya kwi-5.25 V yombane.I-AD7888 iyakwazi ukuphumelela i-125 kSPS.I-input track-andhold ifumana isignali kwi-500 ns kwaye ibonise iskimu esisodwa sokulinganisa isampuli.I-AD7888 iqulethe iigalelo ze-analog ezisibhozo ezinesiphelo esisodwa, i-AIN1 nge-AIN8.Igalelo le-analog kwitshaneli nganye kwezi lisuka ku-0 ukuya kwi-VREF.Inxalenye iyakwazi ukuguqula izibonakaliso zamandla apheleleyo ukuya kwi-2.5 MHz. I-AD7888 ibonisa i-on-chip 2.5 V ireferensi enokusetyenziswa njengomthombo wesalathisi kwi-A / D converter.I-REF IN/REF OUT pin ivumela umsebenzisi ukufikelela kwesi singqinisiso.Kungenjalo, le pin inokuqhutywa ngaphezulu ukuze ibonelele ngombane wesalathiso wangaphandle we-AD7888.Uluhlu lwamandla ombane kule referensi yangaphandle lusuka kwi-1.2 V ukuya kwi-VDD.CMOS ulwakhiwo luqinisekisa ukuchithwa kwamandla aphantsi okuqhelekileyo kwe-2 mW ngokusebenza okuqhelekileyo kunye ne-3 µW kwimowudi yokuhla kwamandla. I-SOIC) kunye ne-16-lead encinci ye-shrink encinci ye-outline (TSSOP) iphakheji.
IIMBALASANE ZEMVELISO
Incinci i-12-bit 8-channel ADC;I-TSSOP ye-16-lead yindawo efanayo kunye ne-SOIC ekhokelayo ye-8 kwaye ingaphantsi kwesiqingatha sobude. Amandla aphantsi kakhulu i-12-bit 8-channel ADC.Izinketho zolawulo lwamandla eziguquguqukayo ezibandakanya amandla okuzenzekelayo emva kokuguqulwa.Uluhlu lwegalelo lwe-Analog ukusuka kwi-0 V ukuya I-VREF (VDD).5. I-Port Versatile serial I / O port (SPI / QSPI / MICROWIRE / DSP Iyahambelana).
