DESCRIPTION

The SP8528 is a very low power 12-Bit A/D converter. The SP8528 typically draws 230µA of

supply current when sampling at 33.2 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 SP8528 is available in 8-Pin NSOIC packages, specified over Commercial

and Industrial temperature ranges. The SP8528 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.
