Two-channel SAR ADC in a compact 8-pin package
The ADC102S021CIMM/NOPB: The internal multiplexer cycles through the two channels, feeding the sample-and-hold and then the SAR engine — no external mux needed for a two-sensor readout. The serial interface is SPI- and DSP-compatible, so it talks directly to the SPI port on most MCUs or the serial port on a DSP without glue logic.
Supply range and reference simplicity
The reference type is Supply, meaning the ADC uses the analog supply rail as its voltage reference — no external reference IC needed, but the supply must be clean and stable because any noise on Vdd appears directly in the conversion result.
Housed in an 8-VSSOP package (also listed as 8-TSSOP, 8-MSOP with a 0.118-inch, 3.00 mm width), the footprint is a standard small-outline that fits tight mixed-signal layouts. Cut Tape works for prototype or low-volume builds.
RoHS3 compliant (lead-free), which meets the EU RoHS directive for electronic equipment placed on the market.
