The internal reference and track/hold simplify the external BOM — just a 5V supply and a few decoupling caps. Typical applications include industrial sensor acquisition, battery monitoring, and data-logging systems where moderate speed and multi-channel scanning are needed. ## Input configuration — six differential or twelve single-ended The input mux offers six differential or twelve single-ended inputs. The SAR architecture and 1:1 S/H-to-ADC ratio give each channel its own sample-and-hold. ## Supply and interface — 5V rail, I2C bus Both analog and digital supplies run at 5V, so the ADC's full-scale range matches a 0–5V input span without external level shifting. The I2C interface uses standard 100 kHz or 400 kHz clock rates; the ADC's own conversion clock is internal, so the bus speed doesn't limit throughput. The 5V supply is common in industrial 24V systems after a simple 5V regulator, keeping the power rail clean.","metaTitle":"MAX1238EEE+ 12-bit SAR ADC, 94.4 kS/s, I2C, 16-QSOP","metaDescription":"MAX1238EEE+ 12-bit SAR ADC from Analog Devices. 94.4 kS/s sampling rate, I2C interface, 6 differential or 12 single-ended inputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"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":"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":"$19.73","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$19.73000","currency":"USD"},{"qty":10,"price":"$18.12800","currency":"USD"},{"qty":25,"price":"$17.37720","currency":"USD"},{"qty":100,"price":"$15.31060","currency":"USD"},{"qty":300,"price":"$14.55913","currency":"USD"},{"qty":500,"price":"$13.61984","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX1236-MAX1239M.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the MAX1238EEE+ work with 3.3V logic?","answer":"No — the digital supply is specified at 5V, so the I2C bus must operate at 5V logic levels.
