♠ Product Description
AD7734 yog qhov siab precision, high throughput analog pem hauv ntej kawg. Qhov tseeb 16-ntsis pp daws teeb meem yog ua tiav nrog tag nrho lub sijhawm hloov pauv ntawm 500 μs (2 kHz channel hloov), ua rau nws zoo tagnrho rau cov kev daws teeb meem siab multiplexing.
Cov cuab yeej tuaj yeem teeb tsa los ntawm qhov yooj yim digital interface, uas tso cai rau cov neeg siv sib npaug ntawm cov suab nrov tawm tsam cov ntaub ntawv dhau mus txog 15.4 kHz.
Lub analog pem hauv ntej kawg nta plaub ib leeg-kawg input channel nrog unipolar lossis qhov tseeb bipolar input ranges rau ± 10 V thaum ua haujlwm los ntawm ib qho + 5 V analog mov. Cov cuab yeej muaj qhov sib txawv thiab tsis pom kev muaj peev xwm nrhiav tau thiab lees txais qhov kev tawm tswv yim analog overvoltage rau ± 16.5 V yam tsis muaj kev cuam tshuam qhov kev ua tau zoo ntawm cov kab uas nyob ib sab.
Qhov sib txawv siv input nta "No-Reference" ntes muaj peev xwm. ADC kuj tseem txhawb nqa ib txoj kab ke kev ntsuas kev xaiv. Lub digital serial interface tuaj yeem teeb tsa rau 3-xaim kev ua haujlwm thiab sib xws nrog microcontrollers thiab digital teeb liab processors. Tag nrho cov interface inputs yog Schmitt triggered.
Cov cuab yeej tau teev tseg rau kev ua haujlwm dhau qhov kev lag luam txuas ntxiv ntawm -40 ° C txog + 105 ° C.
Lwm yam khoom siv hauv tsev neeg AD7734 yog AD7732 thiab AD7738.
AD7732 zoo ib yam li AD7734, tab sis nws cov analog pem hauv ntej kawg nta ob qhov sib txawv ntawm cov tswv yim sib txawv.
AD7738 analog pem hauv ntej kawg yog configurable rau plaub tag nrho sib txawv los yog yim ib leeg-kawg input channel, nta 0.625 V rau 2.5 V bipolar / unipolar input ranges, thiab lees txais ib hom input voltage ntawm 200 mV rau AVDD - 300mV.
AD7738 multiplexer tso zis yog pinned tawm sab nraud, tso cai rau tus neeg siv los siv qhov programmable nce lossis teeb liab txias ua ntej siv rau ADC.
