GENERAL DESCRIPTION
Iyo AD7888 inomhanya zvakanyanya, yakaderera simba, 12-bit ADC inoshanda kubva kune imwechete 2.7 V kusvika 5.25 V magetsi.Iyo AD7888 inokwanisa kuita 125 kSPS throughput rate.Iyo yekupinza track-andhold inowana chiratidzo mu500 ns uye inoratidza imwechete-yakapera sampling chirongwa.Iyo AD7888 ine sere-yakapera analogi yekupinda, AIN1 kuburikidza neAIN8.Iyo analog yekupinda pane imwe neimwe yeiyi chiteshi kubva ku0 kuenda kuVREF.Chikamu chinokwanisa kushandura zviratidzo zvemasimba akazara kusvika ku 2.5 MHz. Iyo AD7888 inoratidzira pa-chip 2.5 V referensi iyo inogona kushandiswa sechinyorwa chekushandura kweA / D.Iyo REF IN/REF OUT pini inobvumira mushandisi kuwana iyi referensi.Neimwe nzira, pini iyi inogona kukwiridzirwa kuti ipe yekunze referensi voltage yeAD7888.Mhepo yemagetsi yeiyi referensi yekunze inobva ku1.2 V kuenda kuVDD.CMOS kuvaka inovimbisa kupera simba kwakaderera kweanowanzo 2 mW yekushanda kwakajairika uye 3 µW musimba-pasi mode. SOIC) uye 16-lead yakaonda shrink diki rondedzero (TSSOP) package.
ZVINOKOSHA ZVAKAITIKA
Diki 12-bit 8-chiteshi ADC;16-lead TSSOP inzvimbo imwechete ne8-lead SOIC uye isingasviki hafu yehurefu.Lowest Power 12-bit 8-channel ADC.Flexible power management options kusanganisira automatic power-down after conversion.Analog input range kubva ku0 V kusvika VREF (VDD).5. Versatile serial I / O port (SPI / QSPI / MICROWIRE / DSP Inoenderana).
