Ulawulo nangona kunjalo lujongano lwedijithali olunentambo ezine kumlawuli wokubamba owenza iiwotshi ukuya kuthi ga kwi-24MHz kwaye iyahambelana ne-SPI, QSPI, Microwire kunye nezinye iiprotokholi.
Linye lamajelo amane kwelinye icala le-chip linokulungiswa kwesoftware njenge:
- Igalelo leVoltage (0-10V, 200kΩ ukhetho lomthwalo)
- Igalelo langoku (Resistor yangaphandle)
- Iziphumo zeVoltage (0-11V)
- Imveliso yangoku (0-25mA, HART ukuthobela ukhetho)
- Ungeniso lwedijithali (ukhetho lwe-de-bounce, utshintsho lwangaphandle, umzekelo)
- Ukulinganisa ubushushu be-sensor (RTD)
Igalelo lixhaswe yi-16-bit enye, Σ-∆ ADC ekwabelwana ngayo phakathi kweendlela ezine- ngokuzikhethela i-50 Hz kunye ne-60 Hz ukwala- kwaye ijelo ngalinye lifumana i-monotonic 13bit DAC. Imilinganiselo yokubhekisa ngaphandle ingasetyenziswa endaweni yesalathiso sangaphakathi.
Njengoko i-chip, ebizwa ngokuba yi-AD74113R, yenzelwe ukuba isetyenziswe kwiimodyuli zesiphelo se-screw, imigca ye-IO ikhuselekile kwaye iyanyamezelana ne-± 40 Vdc.
Impompo ye-chip-yentlawulo-yempompo yenza umzila kaloliwe ongalunganga ukuze iziphumo zikwazi ukufikelela kuyo yonke indlela eya ku-0V.
Imowudi yegalelo levoltage inokulinganisa ii-thermocouples ngokukhetha ± 104.16mV uluhlu lokufaka ngerejista yangaphakathi.
Kukwakho novavanyo lwangaphakathi lobushushu ± 5 ° C.
Ikhawuntari yokufaka igalelo iyafumaneka kwimowudi yokufaka yedijithali.
Ukuze isebenze, i-IC ifuna imizila emithathu yamandla: i-analog (14 - 28.8V), yedijithali yangaphakathi (2.7 - 5.5V) kunye nomnxibelelanisi wokubamba (1.7 - 5.5V). Ezi zimbini zokugqibela zinokwabelana ngonikezelo, kwaye ujongano lomamkeli lunokuba sezantsi njenge-1.8V ukuvumela unxibelelwano lwe-SPI kwi-1.8V. Ii-LDO ezahlukeneyo zangaphakathi ziyafumaneka ukunceda ekunikezeleni ngombane. Isitimela esenziwe ngaphakathi asifumaneki kwimithwalo yangaphandle.
Ukusebenza kungaphaya kwe -40 ° C ukuya kwi-105 ° C, kwaye iphakheji yi-LFCSP engama-64 ekhokelayo
Uhlobo olungabizi kakhulu olungenazinto zininzi ze-chip, ngaphandle kwe-HART, yi-AD74412R.
I-EV-AD74413RSDZ yibhodi yovavanyo ye-AD74413R kwaye inokulawulwa kwi-PC ye-USB kunye ne-Analog's SDP-S inkqubo yokubonisa iqonga (SDP). Ukubonelelwa nge-14 ukuya kwi-28.8V kuyafuneka.
