Texas Instruments ADS124S0x 저전력 아날로그-디지털 컨버터
Texas Instruments ADS124S0x 저전력 ADC(아날로그-디지털 컨버터)는 정밀 24비트 델타-시그마(ΔΣ) ADC로서 소비 전력이 적습니다. ADS124S0x에는 소형 신호 센서를 측정하는 애플리케이션에서 시스템 비용과 구성 부품 수를 줄일 수 있는 다양한 기능이 통합되어 있습니다. 이 ADC에는 짧은 지연 시간에 변환 결과를 제공하고 잡음이 심한 산업 환경에서 50Hz 또는 60Hz 제거 기능을 가진 구성 가능한 디지털 필터가 있습니다.
These Texas Instruments ADCs feature configurable digital filters that offer low-latency conversion results and 50Hz or 60Hz rejection for noisy industrial environments. A low-noise, programmable gain amplifier (PGA) provides gains ranging from 1 to 128 to amplify low-level signals for resistive bridge or thermocouple applications.
Additionally, these devices integrate a low-drift, 2.5V reference that reduces printed circuit board (PCB) area. Finally, two programmable excitation current sources (IDACs) allow for easy and accurate RTD biasing.
