Sigma-delta ADCs come in 16 to 24-bit resolution, and they are economical for most data acquisition and instrument applications. Figure 2.03 (2.04) Integration time Discharge time

Iterates and produces a serial bit stream Output is a serial bit stream with # of 1’s proportional to V in With this arrangement the sigma-delta modulator automatically adjusts its
