DESCRIPTION
The SP8527 is a very low power 10-Bit A/D converter. The SP8527 typically draws 230µA of supply current when sampling at 38.3 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 SP8527 is available in 8-Pin NSOIC packages, specified over Commercial and Industrial temperature ranges. The SP8527 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 wires.
