It samples at 300k samples per second over an SPI serial interface, making it a fit for moderate-speed data acquisition where channel count matters more than high resolution. The part operates from a single 5V supply for both the analog and digital sections, simplifying rail planning. It accepts either an external or internal voltage reference, giving the designer flexibility to match the ADC's full-scale range to the sensor output swing. Housed in a 24-pin SSOP (0.154\" body width) and also offered as a 24-QSOP supplier device package, the MAX11642EEG+ is a surface-mount part suited for compact, mixed-signal PCBs where board area is constrained. The operating temperature range of -40°C to +85°C covers industrial and outdoor telecom environments. ## 16 channels, one conversion engine — what the architecture means The 1:1 S/H-to-ADC ratio and single-ended input configuration mean all 16 analog inputs share one sample-and-hold and one converter. Channel-to-channel skew is determined by the conversion time plus the multiplexer settling; for the 300 ksps aggregate rate, each channel sees roughly 18.5 µs of conversion time when scanning all inputs sequentially. This matters if the application needs near-simultaneous sampling of multiple signals — a simultaneous-sampling ADC would be a different architecture. The 8-bit resolution yields 256 code steps. For a 5V reference, the LSB size is 19.5 mV. That is adequate for monitoring power-supply rails, temperature thresholds, or potentiometer feedback where 1% accuracy is sufficient, but not for precision instrumentation or audio. ## Active lifecycle — no LTB risk for new designs The MAX11642EEG+ carries an Active product status with ROHS3 compliance. This part can be specified into new production BOMs without near-term obsolescence risk.","metaTitle":"MAX11642EEG+ ADC, 8-Bit SAR, 16-Ch, 300ksps, 24-QSOP","metaDescription":"MAX11642EEG+ 8-bit SAR ADC from Analog Devices. 16 single-ended inputs, 300k sampling rate, SPI interface, 5V supply, -40°C to +85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Input Type":"Single Ended","Architecture":"SAR","Configuration":"S/H-ADC","Mounting Type":"Surface Mount","Data Interface":"SPI","Number of Bits":"8","Package / Case":"24-SSOP (0.154\\\", 3.90mm Width)","Reference Type":"External, Internal","Ratio - S/H:ADC":"1:1","lifecycle_stage":"eol_hot","Number of Inputs":"16","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"24-QSOP","Number of A/D Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V","Sampling Rate (Per Second)":"300k"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.42000","currency":"USD"},{"qty":10,"price":"$5.76900","currency":"USD"},{"qty":25,"price":"$5.45400","currency":"USD"},{"qty":100,"price":"$4.72680","currency":"USD"},{"qty":250,"price":"$4.48440","currency":"USD"},{"qty":500,"price":"$4.02384","currency":"USD"},{"qty":1000,"price":"$3.39360","currency":"USD"},{"qty":2500,"price":"$3.22392","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX11638-MAX11643.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to MAX11642EEG+?","answer":"Within the same 8-bit, 16-channel, SAR ADC family, the closest alternatives share the same pinout and SPI interface. The key differentiator is sampling rate; a lower-speed variant reduces cost if 300 ksps exceeds the application's throughput requirement. Confirm pin compatibility against the datasheet before substituting."},{"question":"What is the input type of MAX11642EEG+?","answer":"The MAX11642EEG+ accepts single-ended analog inputs.
