It samples at 150k samples per second over the SPI bus, making it a compact choice for embedded data acquisition where board area is tight. The 5V analog and digital supply rails are shared — both run on the same 5V rail, so there is no separate AVDD/DVDD split to manage. The SOT-23-8 package (also listed as Supplier Device Package SOT-23-8) keeps the footprint small. Operating temperature spans -40°C to 85°C, the industrial grade. ## 150k samples per second — where it fits and where it doesn't At 150k samples per second, this ADC handles slow-to-moderate signals: temperature, pressure, current sense, potentiometer feedback, and general-purpose analog monitoring. It will not capture audio bandwidth or fast transient events — those need a higher sample rate or a pipelined architecture. The SAR architecture gives cycle-by-cycle conversion with no pipeline delay, so each sample is a fresh measurement. That matters for multiplexed inputs where you need a settled reading per channel without waiting for a pipeline flush. The SPI data interface runs at whatever clock rate the master provides, up to the ADC's maximum. No parallel bus, no extra I/O pins — just three or four wires (SCLK, DIN, DOUT, /CS) to the microcontroller. ## Supply and reference — the 5V constraint Both analog and digital supplies are 5V. The digital supply powers the SPI interface logic, so the SPI output levels are 5V CMOS. The reference is external (Reference Type: External), so the full-scale range is set by the voltage applied to the REF pin. ## Lifecycle and sourcing The MAX1286EKA+T carries an Active product status and is ROHS3 compliant. For a BOM line, this is a low-risk fit for both prototype builds and production runs.","metaTitle":"MAX1286EKA+T 12-bit SAR ADC, 150k SPS, SOT-23-8","metaDescription":"Maxim MAX1286EKA+T 12-bit SAR ADC, 150k samples/sec, 2-ch single-ended, SPI interface, SOT-23-8, -40 to 85°C.

The key difference is the number of input channels: the MAX1286 has 2 single-ended inputs, while the MAX1287 typically offers a different channel count or configuration.

This is the throughput for continuous conversions over the SPI interface at the rated clock speed."},{"question":"Can MAX1286EKA+T work with 3.3V logic?","answer":"The digital supply is specified at 5V, so the SPI logic levels are 5V CMOS.

A level shifter or voltage divider on the SPI output lines is recommended when interfacing with 3.3V logic."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1286EKAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1286EKAT when reusing this data.
