BISOBANURO RUSANGE
AD7888 ni umuvuduko mwinshi, imbaraga nke, 12-biti ADC ikora kuva kuri 2.7 V kugeza kuri 5.25 V.AD7888 ishoboye igipimo cya 125 kSPS.Iyinjiza-ikurikirana ibona ikimenyetso muri 500 ns kandi ikagaragaza gahunda imwe yo gutoranya icyitegererezo.AD7888 ikubiyemo umunani winjiza inshuro imwe igereranya, AIN1 kugeza AIN8.Kwinjiza analogi kuri buri muyoboro ni kuva kuri 0 kugeza kuri VREF.Igice gifite ubushobozi bwo guhindura ibimenyetso byuzuye bigera kuri 2.5 MHz. AD7888 igaragara kuri on-chip 2.5 V yerekanwe ishobora gukoreshwa nkisoko yerekana A / D ihindura.REF IN / REF OUT pin yemerera uyikoresha kugera kuriyi nyandiko.Ubundi, iyi pin irashobora kurenza urugero kugirango itange voltage yo hanze ya AD7888.Umuvuduko wa voltage kuriyi nyandiko yo hanze ni kuva kuri 1,2 V kugeza kuri VDD.CMOS yubaka itanga imbaraga nke zo kugabanuka mubisanzwe mW 2 kugirango ikore bisanzwe na 3 µW muburyo bwo kumanura.Igice kiraboneka mumubiri wa 16-uyobora umubiri muto muto ( SOIC) hamwe na 16-bayobora inanutse igabanya urucacagu ruto (TSSOP).
IBIKURIKIRA
Gitoya 12-bit 8-umuyoboro wa ADC;16-bayobora TSSOP nigice kimwe na 8-bayobora SOIC kandi itarenga kimwe cya kabiri cyuburebure.Ibikoresho bito cyane 12-bit 8-umuyoboro wa ADC.Ibikoresho byoroshye byo gucunga amashanyarazi harimo na power-down-down nyuma yo guhinduka. Analog yinjira kuva 0 V kugeza VREF (VDD).5. Urutonde runyuranye I / O icyambu (SPI / QSPI / MICROWIRE / DSP Ihuza).
