The 1:1 S/H-to-ADC ratio means each conversion samples and holds the selected channel before digitizing — no pipeline delay between channels. For scanning multiple signals, the SPI command selects the next channel; the throughput drops proportionally as you cycle through inputs. If you need simultaneous sampling across channels, this isn't the part — you'd want a multi-ADC device. But for sequential monitoring of 16 points on one bus, the MAX11643EEG+ keeps the wiring simple. ## Lifecycle and sourcing No last-time-buy notice or end-of-life announcement is on record.","metaTitle":"MAX11643EEG+ ADC 8-Bit SAR 300k SPI 16-Ch 24-QSOP","metaDescription":"MAX11643EEG+ 8-bit SAR ADC, 300k samples/sec, 16 single-ended inputs, SPI interface, 2.7V-3.6V supply, -40°C to +85°C, 24-QSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Input Type":"Single Ended","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"8","Package / Case":"24-SSOP (0.154\\\", 3.90mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"16","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"24-QSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"2.7V ~ 3.6V","Voltage - Supply, Digital":"2.7V ~ 3.6V","Sampling Rate (Per Second)":"300k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.23","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.23000","currency":"USD"},{"qty":10,"price":"$5.62400","currency":"USD"},{"qty":25,"price":"$5.36240","currency":"USD"},{"qty":100,"price":"$4.65630","currency":"USD"},{"qty":250,"price":"$4.44704","currency":"USD"},{"qty":500,"price":"$4.05464","currency":"USD"},{"qty":1000,"price":"$3.53146","currency":"USD"},{"qty":2500,"price":"$3.40067","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX11638-MAX11643.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many channels does MAX11643EEG+ have?","answer":"The MAX11643EEG+ has 16 single-ended analog input channels multiplexed into one SAR ADC core."},{"question":"Does MAX11643EEG+ work with 3.3V SPI?","answer":"Yes, the digital supply range of 2.7V to 3.6V means the SPI interface operates at 3.3V logic levels directly — no level translation needed when connecting to a 3.3V microcontroller."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX11643EEG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX11643EEG when reusing this data.
