It offers a configurable input multiplexer that supports either 8 differential or 16 single-ended channels, selectable through the SPI interface. The onboard temperature sensor feature lets you monitor die temperature without an external thermistor — useful for thermal management in multi-channel data acquisition systems where the ADC sits near warm components. ## Package and footprint — 24-QSOP Housed in a 24-pin QSOP (3.90 mm wide, 0.154\" body), the MAX1031BEEG+ uses a fine-pitch surface-mount footprint that saves board area compared to a TSSOP-24. The supplier device package is 24-QSOP; the tube shipping medium is the standard delivery format. ## Lifecycle and sourcing The MAX1031BEEG+ carries an Active product status with ROHS3 compliance.","metaTitle":"MAX1031BEEG+ ADC, 10-Bit SAR, 300k SPS, 24-QSOP","metaDescription":"Maxim MAX1031BEEG+ 10-bit SAR ADC, 300k sampling rate, 8/16 inputs, SPI, -40 to 85°C, 24-QSOP.

The key difference is resolution: the MAX1031 is 10-bit, while siblings like the MAX1030 offer 12-bit resolution at the same sampling rate. Verify the specific order code against your required bit depth before substituting."},{"question":"What does the temperature sensor feature on the MAX1031BEEG+ do?","answer":"The integrated temperature sensor allows the ADC to measure its own die temperature, which can be read through the SPI interface. This is useful for thermal monitoring in systems where the ADC is near heat-generating components like power stages or processors."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1031BEEG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1031BEEG when reusing this data.
