UMHLAHLANDLELA WOKUQALA OKUSHESHAYO WOKUBONISA ICIRCUIT 1383
I-16-BIT DELTA SIGMA ADC NE-I2C INTERFACE
I-LTC2451
DESCRIPTION
Isekethe ye-Demonstration 1383 ifaka i-LTC2451, i-16 bit high performance analog-to-digital converter (ADC) ene-interface ye-I2C. Okokufaka kuyi-bipolar enobubanzi be-Ref-to Ref+. Ubunikazi bomshini sampindlela ye-ling yehlisa okokufaka okumaphakathi kwamanje kube ngaphansi kwama-oda angama-50nA obukhulu obuphansi kune-delta sigma ADCs ejwayelekile. I-LTC2451 itholakala ngamaphini angu-8, iphakheji ye-DFN engu-3x2mm futhi inesixhumi esibonakalayo esisebenziseka kalula se-I2C.
I-DC1383 iyilungu lomndeni wakwa-Linear Technology's Quick Eval™ wamabhodi emiboniso. Idizayinelwe ukuvumela ukuhlolwa okulula kwe-LTC2451 futhi ingase ixhunywe ngokuqondile kumasiginali e-analogi yohlelo lokusebenza oluqondiwe kuyilapho kusetshenziswa ibhodi le-DC590 USB Serial Controller kanye nesofthiwe enikeziwe ukuze kukalwe ukusebenza. Izindiza zaphansi eziveziwe zivumela indawo efanelekile yokujikeleza kwe-prototype. Ngemva kokuhlola ngesofthiwe ye-Linear Technology, amasignali edijithali angaxhunywa kusicubunguli/isilawuli sohlelo lokusebenza lokugcina ukuze kuthuthukiswe isixhumi esibonakalayo se-serial.
Idizayini files zaleli bhodi lesifunda ziyatholakala. Shayela imboni ye-LTC.
I-LTC wuphawu lokuthengisa lwe-Linear Technology Corporation
Umfanekiso 1. Ukusetha Okufanelekile Kwezisetshenziswa Zokulinganisa
INQUBO YOKUQALA NGOKUSHESHA
Xhuma kusilawuli se-DC590 USB Serial usebenzisa intambo yeribhoni ye-conductor engu-14 enikeziwe. Xhuma i-DC590 ukuze usonge i-PC ngentambo evamile ye-USB A/B. Qalisa isofthiwe yokuhlola ehlinzekwe nge-DC590 noma elandiwe kuyo http://www.linear.com/software.
Uhlelo olulungile luzolayishwa ngokuzenzakalelayo. Chofoza inkinobho ethi QOQA ukuze uqale ukufunda ivolumu yokufakatage. Imininingwane ngezici zesofthiwe ibhalwe kumenyu yosizo yephaneli yokulawula. Amathuluzi ayatholakala edatha yokungena, ukushintsha ireferensi voltage, ukushintsha inani lamaphoyinti eshadini lemigqa kanye ne-histogram, nokushintsha inani lamaphoyinti alinganiselwe esibonisini se-DVM.
Umfanekiso 2. Isithombe-skrini sesofthiwe
UKUSETSHENZISWA KWE-HARDWARE
XHUMANA KU-DC590 SERIAL CONTROLLER
I-J1 iyisixhumi esibonakalayo samandla nesidijithali.
Xhuma kusilawuli se-serial se-DC590 ngentambo yeribhoni ye-conductor engu-14 enikeziwe.
AMA-JUMPERS
I-JP1 - Khetha umthombo we-REF+, kungaba i-LT66605 noma emthonjeni wangaphandle oxhunywe kokuthunyelwe kwe-Ref+ turret.
IZIXHUMANO ZE-ANALOG
Ukuxhumana kwesignali ye-analog kwenziwa ngomugqa wamaposi we-turret emaphethelweni ebhodi. Futhi, lapho uxhuma ibhodi kumjikelezo okhona izindiza zomhlabathi eziveziwe emaphethelweni ebhodi zingase zisetshenziselwe ukwakha uxhumano oluqinile phakathi kwezizathu.
I-GND - Le turret ixhunywe ngqo ezindizeni zangaphakathi zaphansi.
I-VCC – Lona ngumqulu wokuhlinzeka kanye nereferensitage ye-ADC. Ungadonsi noma yimaphi amandla kuleli phuzu.
I-Vin- Lokhu okokufaka ku-ADC
