That throughput, combined with a multiplexed front end (MUX-S/H-ADC) accepting either single-ended or pseudo-differential inputs, makes it a fit for scanning multiple analog channels in industrial control, data-acquisition systems, and instrumentation where moderate speed and 12-bit resolution are the design targets. ## Input flexibility and interface The part supports three or six input channels depending on configuration, with a 1:1 sample-and-hold-to-ADC ratio. The parallel data interface gives deterministic read timing — no serial latency to budget — which matters when the host controller needs a sample on a fixed clock edge. Reference can be internal or external, so you can match the ADC full-scale range to the sensor output without an extra reference IC. ## Supply rails and temperature grade Both the analog and digital supplies run from a single 5 V rail, simplifying the power tree. The -40°C to 85°C operating range covers industrial and outdoor environments — motor drives, remote telemetry, or engine-bay-adjacent electronics — without needing a wider-temperature part. The 28-QSOP package (0.154\" body width) is a compact surface-mount footprint that routes well on a 2-layer board.","metaTitle":"MAX1266BEEI+ ADC, 12-Bit 420ksps, 28-QSOP, Active","metaDescription":"MAX1266BEEI+ 12-bit SAR ADC, 420k samples/sec, parallel interface, MUX-S/H-ADC, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Input Type":"Pseudo-Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"Parallel","Number of Bits":"12","Package / Case":"28-SSOP (0.154\\\", 3.90mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"3, 6","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"28-QSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"420k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$23.8664","stockQuantity":0,"priceTiers":[{"qty":50,"price":"$23.86640","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1266-MAX1268.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does the MAX1266BEEI+ come in?","answer":"It is supplied in a 28-pin QSOP package (0.154\" body width, 3.90 mm width), surface-mount, shipped in Tube form."},{"question":"What is the resolution and sampling rate of the MAX1266BEEI+?","answer":"12-bit resolution with a maximum sampling rate of 420k samples per second.
