The SP8538 is a very low power 12-Bit data acquisition chip.

The SP8538 typically draws 250µA of supply current when sampling at 25 kHz.

Supply current drops linearly as the sample rate is reduced.

Two program bits, which are shifted into the device prior to conversion, determine the input configuration. In the single ended MUX configuration the input signal will be applied to either channel 0 or channel 1 and will be ground referenced. The maximum full scale range is VCC. In the full differential mode, the signal will be applied between channel 0 and channel 1. The signals applied at each input may both be dynamic. This is in contrast with pseudo differential devices which must have input.
