  • Choosing an Optocoupler for the ADS1202 Operating in Mode 1
    PDF, 116 Kb, Datei veröffentlicht: Feb 12, 2003
    The ADS1202 is a precision, 80-dB dynamic range, delta-sigma modulator operating from a single +5-V supply. The differential inputs are ideal for direct connections to transducers or low-level signals. With the appropriate digital filter and modulator rate, the device can be used to achieve 15-bit analog-to-digital conversion with no missing codes. This application report describes how to choose a

  • Digital Filter Types in Delta-Sigma ADCs
    PDF, 219 Kb, Datei veröffentlicht: Jun 27, 2017
    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
