MAX11617EEE+T

Analog To Digital Converters (ADC) Overview

The MAX11617EEE+T is a low-power, 12-bit analog-to-digital converter (ADC) featuring 12 single-ended or 6 fully differential 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 high-speed I²C-compatible serial interface supporting up to 1.7MHz in high-speed mode. It achieves a maximum sampling rate of 94.4ksps with a typical supply current of 670µA. The part is housed in a 16-pin QSOP package and is guaranteed over the extended industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated track-and-hold circuitry with software-configurable unipolar/bipolar and single-ended/differential input modes
• Internal 2.048V voltage reference with support for external references ranging from 1V to VDD
• High-speed 2-wire serial interface compatible with standard I²C protocols at up to 1.7MHz
• AutoShutdown power-down capability that reduces supply current to less than 1µA during idle periods

Analog To Digital Converters (ADC) Applications

• Medical instruments requiring multi-channel signal acquisition
• Battery-powered test equipment needing low quiescent current
• Solar-powered remote systems operating on limited energy sources
• Handheld portable devices constrained by space and power budgets

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and lead-free status. Ensure the intended application environment remains within the specified -40°C to +85°C operating temperature limits. Confirm that the system bus voltage levels are compatible with the 2.7V to 3.6V supply range before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 12-channel multiplexing capability are required within a compact form factor. The internal 2.048V reference simplifies design compared to parts requiring external components. Consider the 16-pin QSOP package dimensions if board space permits, as smaller WLP options exist for other variants in the series.

Analog To Digital Converters (ADC) Part Context

This device belongs to the MAX11612–MAX11617 family of low-power, multi-channel ADCs. While sharing identical pinouts and core architecture with lower channel count variants like the MAX11615, it specifically provides twelve analog inputs. It serves as a direct upgrade path for designs previously utilizing the MAX11606–MAX11611 10-bit series without requiring PCB layout changes.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the MAX11616EEE+, which shares the same 16-pin QSOP footprint but features a 4.096V internal reference instead of 2.048V.
