That is enough for a differential pair or two single-ended signals, but not for a multi-channel scan. The external reference pin gives you flexibility — tie it to the supply rail for ratiometric measurements, or feed a precision reference if the system needs absolute accuracy. No internal reference means one extra part on the BOM, but also no drift worry from an on-chip bandgap. ## Sourcing and lifecycle — active, no end-of-life pressure The MAX157BCUA+ is listed as Active with ROHS3 compliance. That makes it safe to qualify into a new BOM or stock as a field-replacement spare.","metaTitle":"MAX157BCUA+ 10-bit SAR ADC, 108k SPS, SPI, 8-uMAX","metaDescription":"Maxim MAX157BCUA+ 10-bit SAR ADC, 108k samples/sec, SPI interface, 2.7-5.25V supply, 8-uMAX package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Input Type":"Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"10","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Reference Type":"External","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"2","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-uMAX/uSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"2.7V ~ 5.25V","Voltage - Supply, Digital":"2.7V ~ 5.25V","Sampling Rate (Per Second)":"108k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.83","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.83000","currency":"USD"},{"qty":10,"price":"$10.68400","currency":"USD"},{"qty":25,"price":"$10.18680","currency":"USD"},{"qty":100,"price":"$8.84520","currency":"USD"},{"qty":250,"price":"$8.44764","currency":"USD"},{"qty":500,"price":"$7.70226","currency":"USD"},{"qty":1000,"price":"$6.70842","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX157-MAX159.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the resolution and sample rate of MAX157BCUA+?","answer":"The MAX157BCUA+ is a 10-bit SAR ADC with a sampling rate of 108k samples per second. That gives 1024 output codes at up to 108 kHz throughput."},{"question":"Is MAX157BCUA+ compatible with 3.3V logic?","answer":"Yes. The digital supply range is 2.7V to 5.25V, so the SPI interface operates at 3.3V logic levels directly. No level shifter needed between this ADC and a 3.3V microcontroller."},{"question":"Is MAX157BCUA+ obsolete or end-of-life?","answer":"No. The lifecycle status is Active with ROHS3 compliance. No end-of-life notice or last-time-buy is in effect."},{"question":"What are equivalent or replacement parts for MAX157BCUA+?","answer":"Within the same Maxim family, pin-compatible alternatives include the MAX157BCUA+ (this part) and the MAX157BCUA+ with different temperature grades. For a second-source option, check the MAX1240 or MAX1241 series — they share the same 10-bit SAR core and SPI interface but verify pinout against your layout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX157BCUA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX157BCUA when reusing this data.
