SP8538 converter equivalent, micropower sampling 12-bit a/d converter.
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.
The serial port allows efficient data transfer to a wide range of microprocessors and microcontrollers over 3 or 4 wire.
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. The ADC automatically powers down when not performin.
