KUDZULOWA KWAMBIRI
AD7888 ndi liwiro lalikulu, mphamvu yochepa, 12-bit ADC yomwe imagwira ntchito kuchokera ku 2.7 V imodzi mpaka 5.25 V magetsi.AD7888 imatha kutulutsa 125 kSPS.Njira yolowera-andhold imapeza chizindikiro mu 500 ns ndipo imakhala ndi chiwembu chomaliza chimodzi.AD7888 ili ndi zolowetsa zisanu ndi zitatu za analogi imodzi, AIN1 kupyolera mu AIN8.Kuyika kwa analogi pa tchanelo chilichonse ichi ndikuchokera ku 0 kupita ku VREF.Gawoli limatha kutembenuza zizindikiro za mphamvu zonse mpaka 2.5 MHz. AD7888 imakhala ndi chidziwitso cha pa-chip 2.5 V chomwe chingagwiritsidwe ntchito ngati gwero lachidziwitso cha A / D converter.Pini ya REF IN/REF OUT imalola wogwiritsa ntchito kugwiritsa ntchito izi.Kapenanso, pini iyi imatha kuyendetsedwa mopitilira muyeso kuti ipereke mphamvu yamagetsi yakunja ya AD7888.Ma voliyumu amtundu wamtunduwu wakunja akuchokera ku 1.2 V kupita ku VDD.CMOS yomanga imatsimikizira kutayika kwamphamvu kwa 2 mW kuti igwire bwino ntchito ndi 3 µW munjira yotsitsa mphamvu. SOIC) ndi phukusi laling'ono la 16-lead shrink (TSSOP).
ZOYENERA ZA PRODUCT
Chochepa kwambiri cha 12-bit 8-channel ADC;TSSOP yotsogolera 16 ndi malo omwewo ndi SOIC yotsogolera 8 komanso osakwana theka la kutalika. Mphamvu Yotsika Kwambiri 12-bit 8-channel ADC. Zosankha zoyendetsera mphamvu zosinthika kuphatikizapo mphamvu zodziwikiratu pambuyo pa kutembenuka.Kuyika kwa Analog kumachokera ku 0 V mpaka VREF (VDD).5. Doko lapadera la I / O (SPI / QSPI / MICROWIRE / DSP Yogwirizana).
