MAX11611EEE+

Analog To Digital Converters (ADC) Overview

The MAX11611EEE+ is a low-power, 10-bit analog-to-digital converter (ADC) featuring 12 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 a fully differential track-and-hold circuit. It supports a maximum sampling rate of 94.4ksps using an external clock or 53ksps with the internal clock. Communication is handled via a high-speed I2C-compatible 2-wire serial interface supporting up to 1.7MHz. The component is housed in a 16-pin QSOP package and is rated for operation within an extended temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-channel analog multiplexer with software-configurable unipolar or bipolar single-ended and differential input modes.
• Includes an internal 2.048V voltage reference and supports external references ranging from 1V to VDD.
• Features AutoShutdown technology that powers down the device between conversions to minimize power consumption at low throughput rates.
• Supports high-speed I2C communication with fast mode and high-speed mode capabilities.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and lead-free status. Ensure the selected variant matches the required supply voltage range of 2.7V to 3.6V. Confirm compatibility with the I2C slave address 0110101 assigned to this model. Check for RoHS compliance markers on the physical component or datasheet revision history.

Analog To Digital Converters (ADC) Selection Notes

Select the MAX11611EEE+ when twelve analog input channels are required alongside 10-bit resolution. This part is suitable for designs constrained by a 3.3V power supply environment. Consider the internal 2.048V reference if external precision components are undesirable. Verify that the system bus speed supports the required 1.7MHz high-speed mode for optimal data throughput.

Analog To Digital Converters (ADC) Part Context

This component belongs to the MAX11606–MAX11611 family of low-power, multichannel ADCs. It shares pinout compatibility with other members of the series, such as the MAX11610, which features a 4.096V internal reference. The family offers variations in channel count and resolution, allowing designers to scale performance without redesigning the PCB layout.

Analog To Digital Converters (ADC) Replacement Considerations

The MAX11610EEE+ is a pin-compatible alternative within the same series. Designers should note that the MAX11610 uses a 4.096V internal reference compared to the 2.048V reference in the MAX11611. Input voltage ranges must be adjusted accordingly to match the different reference voltages.
