The SP8528 is a very low power 12-Bit A/D converter.

The SP8528 typically draws 230µA of supply current when sampling at 33.2 kHz.

Supply current drops linearly as the sample rate is reduced.

The input sampling scheme is full differential, where the maximum full scale range is VREF. The signal is applied between +IN and -IN. The signals applied at each input may both be dynamic. This is in contrast with pseudo differential devices which must have input low held at a constant level during conversion. The converter will provide significant common mode rejection because of the full differential sampling. Each input independently must remain between ground and Vcc to avoid clamping the i.
