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