LTspice: SAR ADC Driver Interface

High-performance SAR ADCs can offer amazing dynamic range and linearity at faster and faster sample rates. But how do you design the amplifier and interface at the analog inputs? LTspice IV can help. This video shows how to use LTspice to simulate the analog input interface of high-performance SAR ADCs. We will look at charge kick-back, settling time, noise and how to make trade-offs between sometimes conflicting goals.
