Texas Instruments ADS1675
The ADS1675 is a high-speed, high-precision analog-to-digital converter (ADC). The ADS1675 ADC is comprised of a low-drift modulator with out-of-range detection and a dual-path programmable digital filter. The dual filter path allows the user to select between two post-processing filters: Low-Latency or Wide-Bandwidth.FEATURES
