That is enough granularity for most sensor-conditioning and control loops, but the effective resolution at the signal-to-noise ratio may be lower than the raw bit count. 500 kSPS throughput means the ADC completes a conversion every 2 µs. The serial interface must clock out the 12-bit result within that window, so the SPI bus speed needs to be at least 6 MHz to avoid back-to-back sampling gaps.","metaTitle":"ADC121S051CISDX/NOPB ADC 12-bit 1-ch 500 kSPS 6-WSON","metaDescription":"Active-production ADC121S051CISDX/NOPB, 12-bit 1-channel 500 kSPS ADC in 6-WSON package.
