18-bit SAR ADC, 680k SPS — differential input, SPI output
The ADS8883IDGSR is an 18-bit successive-approximation-register (SAR) analog-to-digital converter from Texas Instruments' microPOWER™ series, sampling at 680k samples per second. Its differential input architecture and SPI-compatible serial interface make it a direct fit for precision data-acquisition chains where common-mode rejection and a clean digital handoff matter — think industrial sensor front-ends, portable instrumentation, or battery-powered DAQ modules.
