It accepts either differential or single-ended inputs, configurable as two differential or four single-ended channels via the internal mux. The internal reference option saves an external reference IC when board space is tight. ## Input flexibility and conversion architecture The input mux lets you select two differential pairs or four single-ended channels — the same pinout serves both topologies, so a single PCB layout covers either configuration by changing the firmware mux setting. The 1:1 S/H-to-ADC ratio means each conversion samples the input directly without a pipelined delay. SAR architecture delivers no pipeline latency — the conversion result for a given sample is available at the end of that conversion cycle, making it suitable for multiplexed systems where channel switching happens between conversions. RoHS3 compliant, so it passes the EU material restriction requirements without a waiver. The tube packaging is standard for the 8-µMAX footprint; reel or tape options may be available through alternate order codes.","metaTitle":"MAX1237EUA+ 12-bit SAR ADC, 94.4kSPS, I2C, 8-uMAX","metaDescription":"Analog Devices MAX1237EUA+ 12-bit SAR ADC, 94.4kSPS sampling rate, I2C interface, differential/single-ended inputs, 8-uMAX package, -40 to +85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"I²C","Number of Bits":"12","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"2, 4","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-uMAX/uSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"2.7V ~ 3.6V","Voltage - Supply, Digital":"2.7V ~ 3.6V","Sampling Rate (Per Second)":"94.4k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.09","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.09000","currency":"USD"},{"qty":10,"price":"$12.95000","currency":"USD"},{"qty":25,"price":"$12.41360","currency":"USD"},{"qty":100,"price":"$10.93730","currency":"USD"},{"qty":250,"price":"$10.40048","currency":"USD"},{"qty":500,"price":"$10.06500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7da318303a2d524dbfa6bd8a97f1b881.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What input types does the MAX1237EUA+ support?","answer":"It supports both differential and single-ended inputs.
