It accepts differential, pseudo-differential, or single-ended inputs. ## Industrial temperature grade and package Rated for -40°C to 85°C operation, the MAX1249BEEE is specified for factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics where commercial-grade parts drift out of spec. The 16-pin SSOP (3.90 mm width) and the alternate 16-QSOP supplier package keep board footprint small — useful for dense analog front-end cards or multi-channel data-logger modules. The part is surface-mount only; no through-hole variant exists. ## Serial interface and external reference Data transfer uses a standard SPI, QSPI, or MICROWIRE serial interface — no proprietary handshake, so it connects directly to most MCU SPI peripherals or FPGA soft-cores. The reference is external, meaning the designer picks the voltage reference that sets the LSB size and drift profile. That gives control over full-scale range and noise performance independent of the ADC supply. ## RoHS status — plan your compliance review The MAX1249BEEE is listed as RoHS non-compliant. If your BOM requires RoHS exemption or if you ship into EU/China markets with strict RoHS enforcement, factor in a compliance review or a lead-free alternative.","metaTitle":"MAX1249BEEE 10-bit SAR ADC, 133k SPS, 16-SSOP","metaDescription":"MAX1249BEEE 4-channel 10-bit SAR ADC from Maxim Integrated. 133k samples/sec, SPI interface, -40 to 85°C.

Connect the SCLK, DIN, DOUT, and CS pins to the corresponding SPI master pins. The external reference voltage is applied to the REF pin. No level shifters are needed if the master runs at the same supply voltage (2.7 V to 5.25 V)."},{"question":"What are the alternatives to MAX1249BEEE?","answer":"Within the same family, pin-compatible alternatives include the MAX1248 (2-channel, 10-bit) and the MAX1247 (4-channel, 12-bit). For a lead-free option, check the MAX1249BESA+ (SOIC package, RoHS compliant). Verify pinout and electrical specs against your design before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1249BEEE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1249BEEE when reusing this data.
