The differential mode is the better pick when your sensor ground is a few hundred millivolts away from the ADC ground — the SAR core sees the difference, not the offset. Single-ended mode doubles channel count at the cost of sharing the return path. Both modes feed the same 10-bit SAR core, so resolution stays 10 bits regardless of configuration. ## I²C bus and 5V-only supply The digital interface is I²C, so it needs only two wires (SCL, SDA) plus the 5V rail and ground. No parallel bus, no SPI chip-select — just a device address and a start condition. ## Lifecycle and sourcing posture That means it is a safe choice for a new BOM line or a production sustainment contract. It is also ROHS3 compliant, so it passes the EU material restrictions without an exemption.","metaTitle":"MAX1138EEE+ 10-bit SAR ADC, 94.4ksps, I²C, 16-QSOP","metaDescription":"Maxim MAX1138EEE+ 10-bit SAR ADC with 94.4k sampling rate, I²C interface, 6/12 input channels, single 5V supply, -40°C to +85°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Input Type":"Differential, Single Ended","Architecture":"SAR","Configuration":"MUX-S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"I²C","Number of Bits":"10","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"6, 12","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-QSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"94.4k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.13","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.13000","currency":"USD"},{"qty":10,"price":"$12.98200","currency":"USD"},{"qty":25,"price":"$12.44440","currency":"USD"},{"qty":100,"price":"$10.96440","currency":"USD"},{"qty":250,"price":"$10.42624","currency":"USD"},{"qty":500,"price":"$9.75356","currency":"USD"},{"qty":1000,"price":"$8.94638","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1136-MAX1139M.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX1138EEE+ compatible with 5V logic?","answer":"Yes — both the analog and digital supplies are rated for 5V. The I²C interface operates at 5V logic levels. If your microcontroller runs at 3.3V, check that its I²C pins are 5V-tolerant and that the logic-high threshold meets the ADC's VIH minimum (typically 0.7 × DVDD, or about 3.5V at 5V supply)."},{"question":"How to interface MAX1138EEE+ with a microcontroller?","answer":"Connect SCL and SDA to the microcontroller's I²C bus with pull-up resistors (typically 4.7 kΩ to 5V). The ADC address is set by the logic level on the ADD pin — tie it high, low, or leave it floating for one of three addresses. Send a start condition, the device address byte, then a configuration byte to select the input channel and reference mode. Read back two bytes for the 10-bit result (left-justified in a 16-bit word)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX1138EEE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX1138EEE when reusing this data.
