0 LSB Max INL Guaranteed No Missing Codes 8-Pin NSOIC Plastic Package Low Power @ 230µA including Automatic Shutdown: 1nA (typ) Full differential input stage Single Supply 3.
0V to 5.
5V operation Half Duplex Digital Serial Interface Sample Rate: 30.
12µS Pin Compatible Upgrade to LTC 1286 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.
