Micropower Sampling 12-Bit A/D Converter

DESCRIPTION The SP8538is a very low power 12-Bit data acquisition chip. The SP8538typically draws 250µA of supply current when sampling at 25 kHz. Supply current drops linearly as the sample rate is reduced. The ADC automatically powers down when not performing conversions, drawing only
