MAX11611EEE+T

Analog To Digital Converters (ADC) Overview

The MAX11611EEE+T is a low-power, 10-bit analog-to-digital converter (ADC) featuring 12 multiplexed analog input channels. It operates from a single supply of 2.7V to 3.6V and includes an internal 2.048V voltage reference. The device utilizes a successive-approximation architecture with an I²C-compatible 2-wire serial interface supporting up to 1.7MHz clock speeds. It achieves a maximum sampling rate of 94.4ksps with a typical supply current of 670µA. Supply current reduces below 230µA at rates under 46ksps and drops to less than 1µA in shutdown mode via AutoShutdown™ technology. The component is housed in a 16-pin QSOP package and is rated for operation over the extended industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-channel analog multiplexer with fully differential track-and-hold circuitry and software-configurable unipolar or bipolar input modes.
• Features an internal 2.048V voltage reference with provisions for external reference inputs ranging from 1V to VDD.
• Supports high-speed I²C communication with fast mode up to 400kHz and high-speed mode up to 1.7MHz.
• Incorporates AutoShutdown™ functionality to minimize power consumption during idle periods between conversions.

Analog To Digital Converters (ADC) Applications

• Handheld portable instruments
• Medical instrumentation
• Battery-powered test equipment
• Solar-powered remote systems
• Received-signal-strength indicators

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix corresponds to the specific package type and tape-and-reel configuration required for your assembly process. Confirm the lead-free and RoHS compliance status matches your environmental regulations. Ensure the supplier provides valid traceability documentation for the Analog Devices Inc./Maxim Integrated manufacturing source.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution with 12 channels is required within a compact 16-pin QSOP footprint. It is suitable for designs operating on 3.3V supplies where low average power consumption is critical. Consider alternative pin-compatible models like the MAX11610 if a 4.096V internal reference or 5V operation is preferred instead of the 2.048V reference provided here.

Analog To Digital Converters (ADC) Part Context

This part belongs to the MAX11606–MAX11611 family of low-power, multichannel ADCs. It shares architectural similarities with the 8-bit MAX11600 series and the 12-bit MAX11612 series, offering pin compatibility across resolutions. The MAX11611 specifically addresses applications requiring higher channel counts than the 4-channel or 8-channel variants while maintaining low power profiles.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX11610, which differs by utilizing a 4.096V internal reference and supporting 4.5V to 5.5V supply voltages. Other family members such as the MAX11609 provide 8 channels, and the MAX11607 offers 4 channels in smaller packages.
