DESCRIPTION  
The SP8538 is a very low power 12-Bit data acquisition chip. TheSP8538 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 performing conversions, drawing only  
leakage current. The SP8538 is available in 8-Pin NSOIC packages, specified over Commercial  
and Industrial temperature ranges. The SP8538 is best suited for Battery-Operated Systems,  
Portable Data Acquisition Instrumentation, Battery Monitoring, and Remote Sensing  
applications. The serial port allows efficient data transfer to a wide range of microprocessors and  
microcontrollers over 3 or 4 wires.
