The Sigma-Delta ADC is a high-resolution sigma-delta analog-to-digital converter. The latency is only one effective data output period (40ns at fCLK=50MHz), which makes the converter ideally suited for application in closed-loop digital control systems. The low latency is enabled by feedback of the bit stream output into a DAC with built-in filtering. This results in a “tracking ADC behavior”, where the output accurately tracks the input signal within the signal bandwidth. The filtering DAC makes the system robust against jitter and other error sources typically associated with 1-bit converters.
