ʻO ka wehewehe ʻana no ka ADS1147
ʻO nā mea hana ADS1146, ADS1147, a me ADS1148 he pololei, 16-bit analog-to-digital converters (ADCs) i loaʻa nā hiʻohiʻona i hoʻohui ʻia e hōʻemi i ke kumukūʻai ʻōnaehana a me ka helu ʻāpana no nā noi ana sensor.Hōʻike nā mea hana i ka haʻahaʻa haʻahaʻa, programmable gain amplifier (PGA), kahi delta-sigma (ΔΣ) ADC me kahi kānana kikohoʻe hoʻonohonoho hoʻokahi, a me kahi oscillator kūloko.Hāʻawi pū nā mea hana ADS1147 a me ADS1148 i kahi kuhikuhi i kūkulu ʻia, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ʻelua mau kumu hoʻohālikelike programmable excitation current (IDACs).
Kākoʻo ka mea hoʻokomo multiplexer i ʻehā mau mea hoʻokomo ʻokoʻa no ka ADS1148, ʻelua no ka ADS1147, a hoʻokahi no ka ADS1146.Eia kekahi, hoʻohui ka multiplexer i ka ʻike ʻana i ka puhi ʻana i ka ʻike, ka bias voltage no nā thermocouples, ka nānā ʻana o ka ʻōnaehana, a me nā kumu nui digital I/Os (ADS1147 a me ADS1148).Hāʻawi ka PGA i nā lanakila koho a hiki i 128 V/V.Hāʻawi kēia mau hiʻohiʻona i ka hopena mua-hope piha no nā noi ana ʻana i ke ana wela e like me nā thermocouple, thermistors, a me nā mea ʻike wela pale (RTD) a me nā ana hōʻailona liʻiliʻi ʻē aʻe me nā mea ʻike alahaka resistive.Noho ka kānana kikohoʻe i ka pōʻai hoʻokahi e kākoʻo i ke kaʻa uila wikiwiki i ka wā e hoʻohana ai i ka multiplexer hoʻokomo a hāʻawi i nā helu ʻikepili a hiki i 2 kSPS.No ka helu ʻikepili o 20 SPS a i ʻole ka liʻiliʻi, ua hōʻole ʻia ka 50-Hz a me 60-Hz interference e ka kānana.
