The SD16/SD16_A module features up to three 16-bit sigma-delta A/D converters with an internal 1.2V reference. Each has up to 8 fully differential multiplexed inputs including a built-in temperature sensor. The converters are second-order oversampling sigma-delta modulators with selectable oversampling ratios of up to 1024 (SD16_A) or 256 (SD16). The Comparator_A/A+ module supports precision slope analog-to-digital conversions, supply voltage supervision, and monitoring of external analog signals for accurate voltage and resistor value measurement. The module features a selectable reference voltage generator and input multiplexer (Comp A+).
