ADS1147 txoj haujlwm tam sim no
ADS1146, ADS1147, thiab ADS1148 cov khoom siv yog qhov tseeb, 16-ntsis analog-rau-digital converters (ADCs) uas suav nrog ntau yam kev sib koom ua ke los txo cov nqi hluav taws xob thiab cov khoom suav rau kev ntsuas ntsuas kev siv.Cov cuab yeej muaj suab nrov qis, programmable nce amplifier (PGA), qhov tseeb delta-sigma (ΔΣ) ADC nrog ib lub voj voog daws teeb meem digital lim, thiab lub oscillator sab hauv.ADS1147 thiab ADS1148 cov khoom siv kuj tseem muab cov khoom siv ua-hauv, tsis tshua muaj hluav taws xob siv hluav taws xob, thiab ob qhov sib koom ua ke ntawm qhov programmable excitation tam sim no (IDACs).
Lub tswv yim multiplexer txhawb nqa plaub qhov sib txawv ntawm cov khoom siv rau ADS1148, ob qho rau ADS1147, thiab ib qho rau ADS1146.Tsis tas li ntawd, multiplexer integrates sensor burn-out detection, voltage bias for thermocouples, system monitoring, and general purpose digital I/Os (ADS1147 and ADS1148).PGA muab kev xaiv nce mus txog 128 V / V.Cov yam ntxwv no muab cov kev daws teeb meem rau pem hauv ntej kawg rau kev ntsuas qhov ntsuas kub nrog rau cov thermocouples, thermistors, thiab cov ntsuas kub tsis kam (RTDs) thiab lwm yam kev ntsuas me me nrog rau cov ntsuas hluav taws xob tiv thaiv.Cov ntxaij lim dej digital nyob hauv ib lub voj voog los txhawb kev nrawm nrawm nrawm thaum siv cov tswv yim multiplexer thiab muab cov ntaub ntawv tus nqi txog li 2 kSPS.Rau cov ntaub ntawv tus nqi ntawm 20 SPS lossis tsawg dua, ob qho tib si 50-Hz thiab 60-Hz cuam tshuam raug tsis lees paub los ntawm lub lim.
