SP8528中文资料SIPEX数据手册PDF规格书

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.
