It belongs to the MAX1111 family of low-power serial ADCs designed for embedded data acquisition where a compact footprint and single-supply operation matter. The input front-end combines a 2- or 4-channel multiplexer with a sample-and-hold, configurable as differential or single-ended. That means a single part handles both ratiometric sensor pairs and single-ended voltage monitoring without an external mux. Data transfers over a standard SPI interface — the serial clock shifts out the conversion result on the falling edge, so the host MCU reads the 8-bit word with any SPI master running at the bus voltage. No separate Vref or Vdd split is needed, which simplifies the power tree on a mixed-signal board. The reference can be driven externally or drawn from the internal bandgap. For ratiometric measurements the external reference pin tracks the sensor excitation; for absolute readings the internal reference holds a stable 2.5 V typical. Surface-mount assembly with a tube shipment format — the tube protects the leads during handling and feeds directly into a pick-and-place feeder with a tube-to-tape adapter. Analog Devices lists the MAX1111CEE+ as Active with ROHS3 compliance.","metaTitle":"MAX1111CEE+ Analog Devices 8-bit SAR ADC, 50k SPS, SPI","metaDescription":"MAX1111CEE+ 8-bit SAR ADC from Analog Devices, 50k sampling rate, SPI interface, 2.7-5.5V supply, 16-QSOP.
