I need 100-dB dynamic range for a medical imaging application. Can you help me choose between successive-approximation and sigma-delta ADC architectures?
Multiplexing allows the use of fewer ADCs per system, offering significant savings in power, size, and cost.
For data acquisition systems, sometimes a successive approximation ADC works best. Other times, a delta-sigma is the best choice. Let's see what works best and why.
