AD7760BSVZ IC ADC 24BIT SIGMA-DELTA 64TQFP

Tsanangudzo

Iyo AD7760 ibasa repamusoro, 24-bit Σ-Δ analog-to-digital converter (ADC).Iyo inosanganisa yakakura yekuisa bandwidth uye yakakwirira kumhanya nemabhenefiti e-Σ-Δ kutendeuka kuti uwane kuita kwe100 dB SNR pa2.5 MSPS, ichiita kuti ive yakanakira yekumhanyisa data kutora.Wide dynamic range yakasanganiswa neyakaderedzwa zvakanyanya antialiasing zvinodiwa inorerutsa maitiro ekugadzira.Iyo yakasanganiswa buffer yekutyaira iyo referefeta, inosiyanisa amplifier yekuvharira chiratidzo uye danho rekuchinja, mureza wepamusoro, kuwana mukati uye marejista ekugadzirisa, uye yakaderera-pass yedhijitari FIR sefa inoita iyo AD7760 compact, yakanyatsobatanidzwa yedata yekutora mudziyo inoda kushoma peripheral. kusarudzwa kwechikamu.Pamusoro pezvo, chishandiso chinopa mareti ekuderedzwa, uye iyo digitaalinen FIR sefa inogona kugadziridzwa kana iyo yakasarudzika maitiro asina kukodzera kuapp.Iyo AD7760 yakanakira zvikumbiro zvinoda yakakwira SNR isina yakaoma yekumberi-yekupedzisira chiratidzo chekugadzirisa dhizaini.Musiyano wekupinza unotorwa sample kusvika ku40 MSPS neanalog modulator.Iyo modulator inobuda inogadziriswa neyakatevedzana yeyakaderera mafirita, ine yekupedzisira sefa ine default kana mushandisi-anorongwa coefficients.Sample chiyero, mafirita ekona frequency, uye kubuda kwemazwi chiyero zvinoiswa nemusanganiswa wekunze wachi frequency uye maregisheni eiyo AD7760.Iyo referensi voltage inopihwa kuAD7760 inotaridza iyo analog yekuisa renji.Iine 4 V referensi, iyo analog yekuisa mutsara ndeye ± 3.2 V kusiyanisa kwakarerekera kune yakajairwa maitiro e2 V. Izvi zvakajairika-mode biasing zvinogona kuwanikwa uchishandisa on-chip differential amplifier, zvichiwedzera kuderedza kunze kwechiratidzo chekugadzirisa zvinodiwa.Iyo AD7760 inowanikwa mune yakavhurika paddle, 64-lead TQFP uye inotsanangurwa pamusoro pemaindasitiri tembiricha kubva -40°C kusvika +85°C.
