Each of the eight internal A/D converters has its own sample-and-hold, so all channels capture the same instant — no skew from multiplexing. That matters for applications like three-phase power monitoring, multi-axis vibration analysis, or simultaneous voltage/current measurements where the phase relationship between channels has to be preserved. ## What the 250 ksps and 16 bits mean for your measurement At 250 ksps per channel, the converter can digitize a 125 kHz bandwidth signal (Nyquist) per channel while all eight run concurrently. The 16-bit resolution gives a theoretical dynamic range of about 96 dB — enough to resolve microvolt-level changes on a 5 V full-scale input without an external amplifier. The SAR architecture means no pipeline latency: the output code for a given sample is available on the parallel bus within one conversion cycle, which simplifies real-time control loops. ## Package and layout — the 56-TQFN exposed pad The MAX11049ETN+ comes in a 56-lead TQFN with an exposed pad (8x8 mm body). The pad must be soldered to a thermal land on the PCB and connected to the analog ground plane with multiple vias — this is the primary heat path. The part draws its analog supply from a single 5 V rail and the digital interface from 2.7 V to 5.25 V, so it can talk directly to 3.3 V or 5 V logic without level shifters. Surface-mount assembly with a standard reflow profile works; no special bake is required if the moisture-barrier bag seal is intact. ## Lifecycle and sourcing Maxim lists the MAX11049ETN+ as Active. The part is ROHS3 compliant.","metaTitle":"MAX11049ETN+ ADC 16-bit SAR 8-Ch 250k, 56-TQFN","metaDescription":"Maxim Integrated MAX11049ETN+ 16-bit SAR ADC, 8 simultaneous-sampling channels at 250k sps, parallel interface, -40 to 85°C, 56-TQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Features":"Simultaneous Sampling","Input Type":"Single Ended","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"Parallel","Number of Bits":"16","Package / Case":"56-WFQFN Exposed Pad","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"8","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"56-TQFN (8x8)","Number of A/D Converters":"8","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"2.7V ~ 5.25V","Sampling Rate (Per Second)":"250k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$34.5","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$34.50000","currency":"USD"},{"qty":10,"price":"$31.82100","currency":"USD"},{"qty":25,"price":"$30.39080","currency":"USD"},{"qty":100,"price":"$27.17300","currency":"USD"},{"qty":250,"price":"$25.92164","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX11047-MAX11059.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX11049ETN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX11049ETN when reusing this data.
