The need for lower power, lower noise analog front-ends (AFE) is becoming increasingly important in many applications today, such as data acquisition systems (DAQs), field instrumentation, Internet-of-Things (IoT), and automatic test equipment. In many cases, this need is highlighted by the advent of high resolution, high SNR, and low-power ADCs, similar to TI’s 24-bit ADS127L01 Delta-Sigma ADC, supported by complimentary low-power, low-noise AFEs. These new solutions will allow system designers to integrate a higher number of channels in data acquisition, wireless metering, and field instrumentation systems. Improved ADC and AFE design solutions will also provide better support and improve numerous power sensitive IoT applications. The TIDA-01013 reference design demonstrates a complete low power, low noise AFE and ADC solution designed to enhance power sensitive applications.
