DescriptionThe ADS8331isa low-power, 16-bit, 500-k samples-
per-second (SPS) analog-to-digital converter (ADC)
witha unipolar, 4-to-1 multiplexer (mux) input. The
device includesa 16-bit capacitor-based successive
approximation register (SAR) ADC with inherent
sample and hold.
The ADS8332 is based on the same core and
includesa unipolar 8-to-1 input mux. Both devices
offera high-speed, wide-voltage serial interface and
are capableof daisy-chain operation when multiple
converters are used.
These converters are availablein 24-pin,4×4 VQFN
and 24-pin TSSOP packages and are fully specified
for operation over the industrial –40°C to 85°C
temperature range.
Device Information(1)(1) Forall available packages, see the orderable addendumat
the endofthe data sheet.
