The SP8538 is a very low power 12-Bit data acquisition chip. The SP8538 typically draws 250A 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. VCC
