Understanding SAR ADCs: Their Architecture and Comparison …

SAR operation (4-bit ADC example). Notice that four comparison periods are required for a 4-bit ADC. Generally speaking, an N-bit SAR ADC will require N comparison periods and will not be ready for the next conversion until the current one is complete. This explains why these ADCs are power- and space-efficient, yet are rarely seen in speed-

AN119: Calculating Settling Time for Switched Capacitor ADCs

If we are using an 8-bit ADC and also want 1/8 LSB accuracy, then this equation becomes: t=ln(256×8)×τ=7.6×τ As shown in Figure 1.1 Equivalent ADC Circuit for Estimating Settling Time on page 1, we estimate the impedance and capacitance to accuracy is about 500 ns, and the 8-bit ADC with 1/8 LSB accuracy is 380 ns.
