Product details
Overview
MAX11616EEE+ from Maxim Integrated is a 12-bit, 12-channel I²C-compatible analog-to-digital converter with internal 4.096V reference, single-supply operation (4.5V–5.5V), 94.4ksps max sampling rate, and ultra-low 670µA active current. It serves as a system-level sensor interface in battery-powered industrial monitoring and portable instrumentation.
For engineers reviewing the MAX11616EEE+ datasheet, MAX11616EEE+ pinout, MAX11616EEE+ application, or MAX11616EEE+ equivalent, key selection criteria include its 12-channel differential/single-ended analog input flexibility, AutoShutdown™ sub-1µA power-down mode, QSOP-16 package compatibility, and guaranteed -40°C to +85°C operation.
Technical Context
The MAX11616EEE+ implements successive-approximation ADC architecture with fully differential track/hold circuitry and an integrated 4.096V voltage reference. Its I²C interface supports both Fast Mode (400kHz) and High-Speed Mode (1.7MHz), enabling rapid configuration and data readout without external clocking overhead.
It features software-configurable unipolar/bipolar and single-ended/differential input modes, internal FIFO with channel-scan capability, and analog input protection diodes allowing safe operation from GND−0.3V to VDD+0.3V - critical for ruggedized sensor front-ends.

FAQ
What is the maximum sampling rate of the MAX11616EEE+ and under what conditions is it achieved?
The MAX11616EEE+ achieves a maximum sampling rate of 94.4ksps when using the internal clock and operating at VDD = 5V with the internal 4.096V reference enabled. This rate is specified across the full -40°C to +85°C temperature range and requires proper decoupling of VDD and AIN11/REF pins. At lower throughput rates (e.g., 40ksps), supply current drops to 230µA, and at 1ksps it falls to just 6µA.
Does the MAX11616EEE+ support differential input configurations, and how many differential channels are available?
Yes, the MAX11616EEE+ supports fully differential input operation. In differential mode, it provides six independent differential input pairs (AIN0–AIN1, AIN2–AIN3, ..., AIN10–AIN11), selectable via the CS[3:0] bits in the configuration register. Each pair is sampled with full 12-bit resolution and benefits from common-mode noise rejection inherent to differential signaling.
Can the MAX11616EEE+ operate with an external reference voltage, and what is the acceptable range?
Yes, the MAX11616EEE+ accepts an external reference voltage applied to the AIN11/REF pin. The valid range is 1V to VDD (i.e., 1V to 5.5V). When using an external reference, the internal 4.096V reference is disabled, and the full-scale code corresponds to the applied VREF. Performance specifications such as INL and THD remain valid across this range, provided the external reference meets required stability and noise requirements.
What package type and pin count does the MAX11616EEE+ use, and is it RoHS-compliant?
The MAX11616EEE+ uses a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch) and is RoHS-compliant and lead(Pb)-free, as indicated by the '+' suffix in the part number. This package offers robust thermal performance and is compatible with standard surface-mount assembly processes, including reflow soldering at up to +260°C peak temperature.
How does the AutoShutdown™ feature function in the MAX11616EEE+, and what is its impact on power consumption?
The AutoShutdown™ feature automatically powers down the MAX11616EEE+ between conversions when no I²C activity is detected, reducing supply current to less than 1µA. This occurs without firmware intervention and is active in all operating modes. At 1ksps, IDD drops to 6µA; at 10ksps, it is 60µA; and at 40ksps, it is 230µA - enabling multi-year battery life in intermittently active sensor nodes.
