The 8:1 S/H-to-ADC ratio means all eight channels sample the same instant — critical for phase-correlated measurements like three-phase power monitoring or multi-axis vibration analysis where a sequential scan would introduce timing skew. Inputs can be configured as differential or single-ended, and the internal reference eliminates the need for an external voltage source on the analog supply rail. ## Supply rails and temperature grade Analog and digital supplies run from 4.75 V to 5.25 V. Operating temperature range is -40°C to 85°C. ## Package and interface Housed in a 28-SOIC wide-body (0.295-inch body width, 7.50 mm), surface-mount. The parallel data interface gives direct connection to an MCU or DSP bus without serial latency — useful when the host needs to read all eight conversion results in a tight loop. ## Lifecycle and sourcing note The part is RoHS non-compliant, so verify your assembly line's exemption status if you're running a lead-free process.","metaTitle":"MAX155BEWI 8-bit ADC, 250k SPS, SAR, 28-SOIC","metaDescription":"MAX155BEWI 8-channel simultaneous-sampling ADC, 250k samples per second, SAR architecture, internal reference, -40°C to 85°C, 28-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Bulk","Features":"Simultaneous Sampling","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"S/H-MUX-ADC","Mounting Type":"Surface Mount","Data Interface":"Parallel","Number of Bits":"8","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","Reference Type":"Internal","Ratio - S/H:ADC":"8:1","lifecycle_stage":"eol_hot","Number of Inputs":"8","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"28-SOIC","Number of A/D Converters":"1","Voltage - Supply, Analog":"4.75V ~ 5.25V","Voltage - Supply, Digital":"4.75V ~ 5.25V","Sampling Rate (Per Second)":"250k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.78","stockQuantity":0,"priceTiers":[{"qty":16,"price":"$18.78000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/977eee2f2f89c6b5c007933afa41b75d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX155BEWI have an internal reference?","answer":"Yes, the MAX155BEWI includes an internal reference, so no external reference IC is needed on the analog supply rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX155BEWI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX155BEWI when reusing this data.
