    1 Features 3 Description The ADS122U04 is a precision, 24-bit, analog-todigital converter (ADC) that offers many integrated
    features to reduce system cost and component count
    in applications measuring small sensor signals. The
    device features two differential or four single-ended
    inputs through a flexible input multiplexer (MUX), a
    low-noise, programmable gain amplifier (PGA), two
    programmable excitation current sources, a voltage
    reference, an oscillator, and a precision temperature
    sensor. 1 Current Consumption as Low as 315 ВµA (typ)
    Wide Supply Range: 2.3 V to 5.5 V
    Programmable Gain: 1 to 128
    Programmable Data Rates: Up to 2 kSPS
    Up to 20 Bits Effective Resolution
    Simultaneous 50-Hz and 60-Hz Rejection at
    20 SPS With Single-Cycle Settling Digital Filter
    Two Differential or Four Single-Ended Inputs ...

    A Basic Guide to Thermocouple Measurements
    Thermocouples are common temperature sensors used in a wide variety of commercial and industrialapplications. While slightly less accurate than resistance temperature detectors (RTDs) thermocouplescover a wide temperature range are self-powered and have a fast response time. Their simpleconstruction make them inexpensive and durable. Because of the small sensor voltage and low noiserequ

    Digital Filter Types in Delta-Sigma ADCs
    This application report discusses digital filters which are a ubiquitous feature in delta-sigma analog todigital converters (ADCs). Digital low-pass filters are essential to the functionality of a delta-sigma ADCwhich relies on oversampling and noise shaping to push quantization noise out of band. There arevariations between the types of digital filters used in delta-sigma ADCs that provide
